We have a wooden floor down in the living room and I think it is slowing the kids down. Aimee would of been walking earlier if it wasn't so slippy. we have just got a huge rug yesterday and already Nathan is getting up on his hands and knees and rocking. Just wondered how long it will be before he goes from this to crawling propally? This is all new to me, Jess never crawled and Aimee comando crawled.
