You're lucky, and must have a typical child.

When my oldest child was 2, he snuck an allen wrench in his diaper and disassembled his whole crib. He is atypical with aspergers syndrome.

You "just don't know" how difficult it is for some children to learn self control through reinforcement.

I have to tell a colleague/friend about this, his kid is quite similar to yours in that respect.
