It seems that with three kids I am always on the go. The poor baby is always being dragged on one errand or another spending many hours a day in his car seat. Unfortunately he wasn't getting the "tummy time" he needed. He was the latest of my kids to roll over and I have to say I started to get concerned. Our house has tile floor that isn't too comfortable for learning to roll over. We also have a dog and a cat so basically the floors are always pretty gross. Last week I got an interlocking playmat with cute dots and holy crap my baby learned to roll over in one day!
