Brayden is 13.5 mths old and is still not walking...barely standing alone. All my kids walked by now except Sarah who has CP. When you start to worry????

well Si turned 1 monday and isnt walking but I am not at all concerned. He is very VERY mobile, just not walking alone yet. My stepfathers brothers kid (hows tht for convoluted, LOL) did not walk until 17 months. The dr said if he wasn't walking at 18m they would worry-- that up until 16 is considered normal-- 16-17 is mildly delayed but still reasonable. Over 18 is of some concern.

Ellery is 13.5 months and not walking. It took her forever to cruise...I think she was 11.5 months when she started. She sometimes stands against things and lets go but it's followed by a crash on her bum. I'm a little worried but I think she'll get it soon.

yes i agree...about 17 months is when i'd be concerned a little.
