My first born never actually crawled at all but second child crawled everywhere

My daughter tended to roll everywhere rather than crawl.

My son was a rocker. Up on all fours just rocking back and forth til he worked out how to move his limbs. My daughter by passed crawling and walked at ten months. I was there the day my grandson first crawled. He crawled straight to me and lay his head in my lap. Still brings a tear to my eye

My baby girl was a bit of a bum shuffler until she realised she could go on all fours, but she’s get stuck in that position! We found it so funny watching her trying to figure it out! She ended up surprising us and took off one day chasing a rolling inflatable toy!
