my 3.5 yr old loves costumes. Just today he dressed as batman, then superman, then batman again, then superman again, then jammies. :) Hats, tool belt, gloves, cape, etc. This kid will dress as a cowboy one day, construction guy the next, then a superhero the next day.
He recently got a Leap Pad game. He's only allowed to use it when he's sitting on the potty trying to poop, so it's kept his attention. I'm pulling out only two stories at a time. Then will pull out the other used ones. (Craigslist!)
This week, I have watched the movie Rio (the bird cartoon that just came out) 6 times. Today was the first day we didn't watch it. And he wanted to! I just said no. The movie is funny IMO and colorful and with great music. The villian (a bird) isn't really that scary. His funniest line "I poop on people and I blame it on seagulls." I totally laughed out loud on that one. :)
Board games? He didn't like Chutes & Ladders. But he likes HiHoCherrio.
Anything with robots, superman, construction. I mean what are your GIRLS into?
