Thank you very much for any input or advice you can give me.
I taught violin (and later cello) lessons for about 40 years. I was not a Suzuki teacher, but I used the Suzuki books (when I "discovered" them after the first 15 years of teaching) because it was clear to me that (in general) they followed the same progression as my own lessons had in the early 1940s. I only had 2 students younger than 6. The cello student was too young.
The 5 year old violin student was only one month old when her teen-age older brother started cello lessons with me. In fact, she was a month-old babe-in-arms when I took the whole family to Ifshin's to select a rental cello for him. She was probably a one-year-old when her next brother (by then a teen, too) started violin lessons with me. By the time she was 2 she wanted violin lessons, so I bought her a VSO (made of cardboard). I held her off until she was 5 and able to read and started her lessons. I taught her mother at the same time so she could help the little girl. Within a month or two the girl was doing better than her mom, whose participation in the lessons then stopped.
The family's trip out of the country and later family problems ended their lessons with me - so I have no idea how things turned out for the little girl. The older brothers were doing fine.
Although my own lessons had started when I was 4, I made it a general rule to wait until kids were 6 before I would take them as students. My own older granddaughter started violin lessons with me when she was 6 and we had just moved closer to her family. We worked together on weekly violin lessons for 10 years, until the end of her sophomore high-school year. I recommend it!
I would not start them until at least age 4 (possibly 5) when they are both ready. In the interim, sign them up for a great general music class.
I've thought about this some more. We both know the physical challenges of playing a violin and how difficult they can be at the beginning.
If I had a child interested in making music at a very young age I would try them on piano. All my kids and grandkids had some piano before going on to other instruments (if they did - and half of them have playing instruments into adulthood). Even I could at least play one-hand piano as a small child and would check out violin-music melodies on piano if I could not "visualize" the sound before reading it on violin.
A piano (or other keyboard) is just THERE. The music starts to come out with the touch of a finger. Of course there are technique and dexterity involved in real piano playing, but not necessarily so. So they can make music from the beginning.
Having seen friends deal with twins, I'd encourage you to treat them as distinct people. If one would be well suited to start now, you could go ahead. The other could decide to follow in their wake, or not, as suits their own personality and interests.
You didn’t mention where you are currently located, but as long as it’s at least a town or even a city, there will be something appropriate.
And when you do enrol them in actual music lessons on an instrument, and your twins are very different as you stated, you may want to think about letting them learn different instruments, so direct comparisons of progress are impossible (that is a sad drawback of the obvious progression in Suzuki programs, which kids (and parents!) can get very competitive about. And it makes for nicer chamber music options at home! How about violin and piano, or violin and cello?
Edited to add an answer to your question about developmental readiness: it’s more about, will they separate from you (depending on the class, some want the parents in the room, some don’t), will they listen to and take directions from another adult, can they function in a group or will they demand constant individual attention? If they do fine in preschool, they’ll do fine in an early music class. But very few kids will be ready to really start learning an instrument at the age of three (yours may be, they’ll usually let you know) and I’d agree that most probably benefit much more from starting around five.
So with your experiences and advice, I will shelf the violin class idea at least one more year. Next year I will re-analyze their development and what they want to do. Also following your advice I will put some structure in the music that I have been free-throwing to them.
We have always had music as an activity which, at their level, used to be rhythmic clapping with patterns (like “we will rock you” using chest and hands) or imitating the patterns I do clapping on my knees, belly, chest, hands, etc a number of times. This, again, showed their difference. She coordinates better but he counts better and corrects her when she mistakes the numbers.
They have sat with me in the piano and I have showed the basic scales. She can replicate my hand actions while he fists the keys. But he recognizes mistakes in the pattern, while she doesn’t see it.
We have a djembe and sometimes I show them some plays on them. Similar story about skills.
They have each a harmonica and they often try to play something; normally together, more often he would play and she would dance. They like to background some songs with their harmonicas.
@Lydia and @Mary Ellen , it is very much my goal to have them in separate instruments; the way this may work is for them to learn 2 (or more) instruments together and then have one of them “drop out” from one. Instantly the other one will drop from the other. But if you try to give them different things from the start, they will destroy each others’ things and hate the activity. They will start violin and piano and let’s see who chooses what, if they do. I would guess that piano would be good for her hand skills, while he can profit of his pitch for violin… But again, they are half baked. Let’s see how they are next year.
Now I have a very specific question, as @Andrew mentions something like that: Under your experience, is it good or bad that they have a violin/VSO now, without classes or training of any kind? I did not want to because I am afraid that they get bad habits with the instrument, or disrespect it as a toy… but it seems that others had it as a preamble to classes. And I think it would calm their itch when they see me practicing. However, I am concern that it eliminates their excitement about learning violin when the time comes… what did you do with your kids?
As a side note, my son seems to be following my childhood habits -- wants to play, doesn't want to quit, doesn't like practicing...
Was musing with a friend how lucky they were that this had worked out for them and what it might mean for (probably) identical twins if one were to have auditioned successfully and the other…not. Maybe the parents took a huge risk there, maybe they were just helplessly watching the twins decide their own path. And it worked out for them and hopefully will continue to do so.
Fraternal boy/girl twins will, at some point, consider themselves very different people, but of course they’re not there yet. But I’d plant the tender seed of the idea of learning different instruments now…
If you can find institutions or individuals who can nurture their talent that goes a long way beyond it being 100% on mom or dad. The economics also matter and are worth thinking through.
We discussed colourstrings which is a Finnish kodaly-influenced violin programme that starts with preschool music and singing and leads into a sol-fa based progression of violin pedagogy, but that's unlikely to be available in Vietnam (although, contact them - you never know).
After reading all the advice about violin vs piano though, I'm tempted to suggest this Irish teacher who specializes in preschool piano: https://colourfulkeys.ie/dublin-piano-school/preschool-lessons/ .
Nicola seems to do alot of pedagogy teaching in the piano teaching world including free resources on her blogs and podcasts. The majority of her resources are piano-specific (or business specific about how to build up a studio), but I got heaps of musical ideas and some free resources that I could transfer to the way I teach strings.

I've not had anyone approach me about piano lessons under 7 years (I teach mostly strings but sometimes piano and occasionally recorder/flute/clarinet to low income beginners), but the moment someone does, I'm going to sign up for the paid subscription to her resource repository - where she apparently has 2 yrs of preschool music lessons.
If you are happy to continue working with them yourself, this might be the way to go - ready made curriculum with downloadable games for small people with short attention spans?
Out of curiosity, how do tiny fingers go with adult sized piano keys? The sound is right there but does hand size interfere with moving from one key to another?
(That said, it's also possible that my teachers avoided octaves for a while. My hands have always been small; I'm still not able to play piano octaves very comfortably as an adult.)

If they are inseparable, I would let them be together including in music instruction.
My own experience with Suzuki instruction as a preschooler was tainted by the terrible sounds created by my classmates. Thus I caution you in this regard. (I rarely hear this brought up. People talk about respecting the instrument. One would think that the experience of music instruction would be at least as important as behavior. Children of this age have well developed memories. They also have probably heard a lot of music. They know terrible sounds when they hear them and can be turned off.)
Respecting the instrument might lead children to believe that they have to be VERY CAREFUL with it at all times and thus discourage them from experimenting in this way. I always waited for my teacher to tell me how to do thins. He just tried what he could do with the instrument. Probably a compromise between these two attitudes might be ideal.
One idea might be to start one twin on violin and the other on piano. They could watch the other's lesson if they liked. They might later take up the respective other instrument. But they would each have something of their own, something they were expert on, that they could also play for relatives without one of them always being "better". I have siblings and one fraternal twin and we always took care to have our own hobbies each. In most aspects, we became interested in opposite subjects, both school and hobby. There are few things as stressful for a sibling as trying to prove you are JUST AS GOOD as your brother or sister, knowing the brother or sister will always be better.
Different instruments would rule out this possibility, until maybe the twins discovered, they they both like the violin and wanted to practice together. Practicing AGAINST you twin, trying to become as good or better as the twin, would probably destroy any kind of progress you could make.
My son is worrisomely careless about many other things, but he handles the violin and bow with both respect and freedom, usually. I don't think they're mutually contradictory.

I started each of my boys around age 3 or 4 with Suzuki violin lessons; in retrospect, that was too early. They were very precocious intellectually but they would have made faster progress from the start had I simply waited until they were 5. Having partially learned a lesson, I did wait until my daughter was closer to 5.
I got them lessons with a colleague who had a lot of Suzuki experience teaching. As it turned out, I was a terrible Suzuki mom. After teaching my own students, I was tired and had to force myself to be the practice mom. It did not help that none of my children were ever excited about playing the violin.
One by one my children got to fifth grade and let me know how much they hated the violin. My oldest switched to double bass at my suggestion; my other two switched respectively to oboe and flute (their choice following recruiting trips by the local middle school band). All excelled on their new instruments.
I don’t think the violin lessons were a waste of time but in retrospect I would have definitely waited until age 5 with all of them. At one point I was also forced into teaching my own children due to my orchestra’s financial difficulties and the departure of their teacher. This was notably unsuccessful.
Three is very young and your twins are not at equivalent levels of readiness by your own description. In your shoes and knowing what I know, I think I would focus on playing them music every day, perhaps even the Suzuki book one recording. I assure you that they will not lose any ground by waiting another year to start lessons.
