A.H.
I have concrete floors and a 4 year old. They are great for cleaning up messes, but are horrible in the winter since they are so cold. I have a huge rug in the living room that helps, but it still keeps the house cold. The only issue I have with my son is if he is wearing only socks. Then he'll slip and slide, but with shoes or barefoot it's not much of a problem. Just this morning he ran through with his socks and slipped on fell on his leg pretty hard. It's got a red mark, but he's ok. That's about the worst accident we've had and I hope we don't have any that are worse! I also agree that things will break easily. I have had a few sippy cups break, a bottle of apple juice that broke, etc. I plan on getting carpet when my son is older and there is less of a chance for carpet stains.
