My 11 month old baby crawls one leg extended. And also while seating her back remains slight curve. The spine is straight while she is standing. Is there anything abnormal? Her other milestones are on time and she is doing her other activity quite well.

A. I think it would be good for you to check with your doctor because when kids sit in this age their spine is completely straight as you mention it is when the child is standing and if the child is walking with support and crawling is okay not a problem the child is keeping one leg apart and walking but you should work on the sitting posture check with your doctor once
