My beautiful little girl is 14 months and does not crawl or walk, she is seeing a physiotherapist and also a paediatrician but is it normal for some babies to be this behind with motor skills?! She is very dinky, only 16lbs. She's healthy and happy which is most important but I can't help but worry, specially when I see 11 month olds run past her in play group! Please don't tell me not to compare because I don't sit and dwell on it at all but obviously it's concerning to see at times ...
