toddlers

my awesome wife just gave birth to an awesome baby. i'm thinking about starting here early on the computer.

are there any PL written for toddlers?

If you mean is there a PL for people who can't read, write, talk or use a computer, then probably not, so focus on teaching her those things first. For children there are languages like Scratch and Logo. In practice, those languages are only used for a few weeks before moving on to something like Scheme. Squeak is made for children but it's horrible. I personally don't see the benefit of languages for children. It's not unheard of for people to start using "real" languages at a very young age.
