Hello! I was wondering if anyone could give me some advice on what age EB's can start going up and down stairs. I have read and heard conflicting advice. We live on the 4th floor of an apartment and there is no elevator so he will have to learn to walk the stairs. When Loki was just 4 months he was walking up the 40 stairs no problem, but then we heard that this is really bad for their joints....so we have gone back to carrying him up and down the stairs. He is now 5 months old and getting pretty heavy! haha. Just wondering what you all think. Thanks!
