Not too worried that my lad isnt crawling just curious, did your late crawlers just take off one day or was there lots of lead up. Saac has been looking like he is going to for about 12weeks, gets from sitting to lying, reaches right over with one leg tucked in position but gets other leg trapped, spins in a circle and pushes backwards. Just wondering whether all the lead up is common or whether some just go from sit to crawl without much in between iykwim. He is 10.5mths.
