How long did it take your little one to work out how to sit down from standing? My daughter has been pulling herself up to stand and cruising for 3 weeks or so, but still hasn't worked out how to get down and cries from frustration to get me to help her. She has fallen a few times onto her bum but doesn't seem to know how to do it herself. She is a commando crawler so not sure if that makes any difference? She's very frustrated and so am I!
