Baby progress

Sambam

Hey everyone! My little boy just turned 9 months. Hes my second and you’d think I’d know the answer by now but the second is so different. He’s not crawling yet, when I put him on the ground for tummy time he rolls himself out very quickly. 😩 my first crawled by like 6 months so this is new territory for me..

Anything I can do besides tummy time to help learn to crawl? I’ve tried so many different toys trying to get him to crawl but he absolutely refuses and rolls out fast.
