Jan - Izzy is the same, shes crawling all over the house now and we have one rug in teh lounge the rest of the house is boards or lino so shes constantly bashing around the place. She pulls herself up to standing on everything and then lets go and falls back - great! As Kellie said I think now they are mobile its a case of they will learn!! Its so hard to watch them hurt themselves though isnt it!
