Ideas to babysit girls?!?

Ok so I babysit these 2 little girls... 4 and 5 months. I pretty much carry the 5 month or put her in a zoomba or a bouncy seat, so that part isn't an issue. The issue is that I babysit them so much that I am running out of ideas. The girl is really girly, but throws a fit when she doesn't get her way and doesn't like to do things that long (she really can be bratty, and if she doesnt get her way she cries and sometimes runs away) but I'm really sick of playing "house because we seriously play that EVERY time. We always color and she doesn't have the patience to bake, I've tried that. We usually play board games, and she doesn't like going on bike rides that much. Help!
