Bump
Christine, I’m not sure how much of this will apply to Myles, but you can check out the section on “to get him on all fours”. We did some/all of these with Hailey and it helped to get her going. Also, just practising and getting more tummy time helped her too. In the end, she finally crawled because she wanted to (even though I’d been trying to get her to do it for ages).
