Crawling but not rolling?

[SaraEmily]

She's just started crawling this week, but still hasn't rolled from back to tummy even once. She's been able to roll the other way since 8 weeks, and onto her side. Is this normal?

Mine has nearly been crawling recently without having known how to roll tummy to back. And actually I think the only way he would have learned to crawl is if he hadn't learned to roll -- now that he can choose not to be on his tummy, I don't think he ever will be again! He's been able to roll back to tummy for a couple months but I've only ever seen him do it once while awake. Don't worry. Congrats on your LO crawling!
