Girls, my son started crawling like a wounded soldier at 7 months old, he's been crawling for a month now, he gets up on all fours but doesn't crawl yet, we got a massage and there's no results yet, we're not getting another massage until we see some progress, when did your kids start crawling? I think maybe he's comfortable crawling, he's used to it and doesn't want to lift his body, he's already crawling as fast as a soldier. Also, when did you start giving him baby food portions? At 6 months, I give him porridge-like baby food. I'm afraid to give him pieces.
