So my daughter is 8 1/2 Months old.

My daughter is almost 9 months in a few days and she doesn’t crawl yet nor does she like to stand on her feet.. like when I hold her up to stand like you do with babies she absolutely will not and she will not put any pressure on them or anything.. I know kids are different but my son crawled by 7m and all my friends babies are all crawling and standing up on everything and they are all younger.. they always tell me to get her checked Idk is it normal? I’ll be bringing it up to her pediatrician tomorrow to ask her but I wanna hear some of your guy’s opinions?
