What she doesn't have are superior fine motor skills and self control when she gets frustrated (which happens easily). She would not be willing to be bossed around by a teacher. She couldn't be trusted not to take her frustration out on her instrument and those suckers are expensive. She would have unrealistic expectations and would expect to be able to perform at a high level sooner than would be possible.
I know dozens of Suzuki kids and all of them had these kind of issues starting up. I know a little boy that spent a year sitting under the piano pouting while his mom used his lesson time to learn piano.
This is why my son didn't start at 3 or 4! Our music school has regular "support groups", to talk about how to work through practice issues. A lot of start up is working through these kind of issues of perfectionism, frustration, and expectations and much less about learning the instrument. The younger you start, the more of this there is to work through. The practice with my 5 year old can involve puppets, stickers, beads, goldfish crackers, etc. It's all a big game to get through those 15 minutes a day!
BUT ... it's a lot easier than it was a year ago.
FWIW, I just don't think you have to have all those ducks in a row to start your child as a preschooler in Suzuki (teachers certainly wouldn't expect it!). But it's good to know that those are the exact kind of things you'll be working on the first year! If you're not into the idea of practicing and being an enthusiastic participant, it's probably best to wait a few years and pursue traditional lessons.
