My boy refused to crawl, would only roll or bum shuffle. Walked at 12 months, first tooth at 10 months and now at 22 months has decided to crawl to get under things lol. My health visitor wasn't concerned and said allot of babies don't crawl
Mine is 9 months and can’t sit up or crawl yet. She can roll, pivot around on her tummy and a few times has pushed herself backwards. She’s going to do everything eventually in her own time so I try not to worry.
My little boy was 10 months when he started crawling we were very worried but he walked at 12 months so it all happened very quickly. I watched soooooo many videos on teaching him to sit from laying down but they’ll just do it in their own time. Every baby is different x
