Do your kids like baths?
Back when my son was a newborn, he could care less if he was taking a bath. After he hit about nine or so months, I think it was, he decided he hated baths. Somewhere between 11 and 12 months, he decided that he loved his baths more than anything and would splash around a lot. My daughter has decided that she hates baths, completely right now, but she is only two months. My stepson loves baths as well and as much as he loves video games, sometimes would rather take a bath than play them! I personally loved baths when I was little.
