My 22m old is not walking yet. Mostly previous milestones were delayed but now he can sit well, stand with support, scoots on bottom, can get down from bed. Crawling is clumsy. Weight is now normal, height ~15 percentile, head circumference ~3 percentile. Speech is now getting better, cognitive is ok. Can recognize number, shapes, alphabets, rhymes & other things. We give him calcium drops additionally. Do you think we should wait or is a neuro assessment required? He underwent physiotherapy for ~3 months.
