9 Months old development
My granddaughter's 9 months old development concerns me. She hasn't turned over yet by herself, she hasn't even tried to sit up yet, doesn't crawl or try to pull up. She seems to be a very happy baby, and if put in a sitting position, she can sit there for quite a long time before falling over, but has no interest in righting herself once she falls.
I am concerned, but don't want to mention it to my daughter if there is no reason for concern. My daughter isn't a very confident Mom, so I don't want to appear to criticize, or alarm her if not necessary.
On the other hand, if the child requires testing to catch something early, I don't want to miss that window of opportunity.
My granddaugter is a very happy baby, and seems to be very bright, but just isn't very physical at all. What's the best I should be doing right now?
