Now, last time I posted about this (when he was 8 months) everyone said not to worry that he will crawl in his own time. I get that. I just want to make sure I'm doing what I'm supposed to be doing to facilitate the crawling.
For example... will he go from sitting to crawling or from tummy to a crawl position? Should I be giving him tummy time? Should I be urging him to crawl? Should he be on a boppy pillow?
In other words... from a developmental perspective babies begin to crawl when "what" happens? Fill in the "what."
I just want to make sure I'm not the one delaying his progress and I want to give him experience doing whatever it is babies do right before they crawl.
