Yasin started weight bearing at about 2 months. The ECHN wasn't worried about it. I think its one of those things thats ok if they want to do it but you shouldn't push them into if they're not interested IYKWIM. Its one of the first stages on the journey to learning to walk so most babies will do it at whatever stage suits them. Nearly all babies are a bit bowlegged when they begin to stand but usually thier legs get straighter in about a year or so.
