My LO jus started walking independently (but still a bit wobbly) at 15+ months.. my mil said he is slow .. I mean , 15 months started walking independently really is considered slow ?

If it makes u feel better, my boy started walking at 18mo 😅 each child has his/her own pace, just let them pick their auspicious date to walk lol i wasn't too concerned since other than walking, he was hitting his milestones. Not walking cld mean a lot of things - not wanting to (maybe just a little lazy), no confidence etc ...
