April 2019 babies

Br

My baby just made 7 months on the 5th. He gets on all 4s, rocks and moves his legs but hasn’t figured out how to move his arms too. He’s been doing that for a while now. He also tries to sit up while he’s in the crawling position but he hadn’t figured that out yet. He does scoot so he goes where he wants. I’m just curious on how many 7 month olds are crawling. Did you help him/her or did he/she just learn on their own?
