This is a list of skills toddlers can learn. Did I forget any?
Learn to Talk, Walk, and Potty Train. The Peg Box and Xylophone. Charisma and Logic with the playpen. Handiness with the walker. Did I forget any?

If you have the drum, then toddlers can gain that skill too, though technically the xylophone works for that. And, as Karritz mentioned they can learn writing and art and logic from toddler books. (I always take my toddlers to the library and have other sims read the toddler books to them there because, as Karritz mentioned, it is much faster skill gain at the library.)
