Not the OP, but why are you laughing at her? We used to walk with our kids when they were that young. Sure, you're not going on day-long hikes, but it's great to get them out on a trail at a Nature Center or something. They love it. And, I'd prefer that, to keeping the kid cooped up inside watching Dora. (nothing against Dora, before I get flamed)
OP, check out any of the Nature Centers. Where are you located? Or, we used to go to Brookside Gardens all the time at that age. DD loved it.
OP, here's a link that might help when DC is a bit older:
