my baby boy will be 8 months old in a few days. For the last month of so he’s constantly getting himself into a crawling position, often into a high plank too, he rocks back and forth and then just either pushes backwards or flips down. He doesn’t seem any closer to moving forwards but he gets soooo frustrated. I’ve tried to encourage him but I think it just makes him more annoyed. Do I try encourage with toys or just leave him to work it out eventually??
