Not worried, just curious. DS has skipped crawling and gone straight to cruising.
I know that is a normal variant, and he’s rolling, commando crawling, sitting, pulling to stand etc so I’m not concerned about him. But I do think he’d find life a lot easier if he could crawl! He gets quite annoyed when he runs out of furniture, and commando crawling is pretty inefficient 
If your child skipped crawling, did they learn how to do it later? Or am I wasting my time trying to teach him when he’d much rather be walking?
