M.O.
It would have been too early for my son, definitely. But you know your baby better than anyone.
My own experience, FWIW, is this: My son came very late to the potty training party. We tried, on and off, but it never seemed to "click." I wound up spending quite some time making our house a "no pants zone." After a while, we graduated to a "underwear only zone." Outside and at preschool, though, N. was still in diapers or pull-ups, even beyond his third birthday. I waited until it was Christmas break, when I would be with him 24/7, and we put him in underwear all day. After that first day, N. was getting himself to the potty just about perfectly -- no tears, no drama, accidents few and far between.
However, my brother tried training my nephew, "E.," at a much younger age -- a little past 2. Basically, it hasn't worked. E is now nearly 3 and has accidents constantly. The whole issue is very fraught with him -- source of all kinds of tears and tantrums. I think he'll get it, eventually, but E. is actually "behind" where N. was at the same age, even though he started much earlier.
So, based on that very limited experience, I'm a fan of waiting. If you really want to try, start by letting him run around naked at home (you might want to wait a month or two, weather wise). Once he can get his naked self to the potty with some regularity, put him in underwear but not yet pants. And so on. The point is to build on successes, not failures. (Let me know if that last part doesn't make sense, and I'll try to explain.)
Good luck!
