Baby girl still doesn't roll over at 7 months

Mrs.S • Happily married with a daughter and a son 🩷💙

So my baby girl doesn't mind tummy time but has only rolled over (from tummy to back) a couple of times and only rolled once from back to tummy. On the other hand she seems to be reaching all her other milestones, she is even sitting down unassisted. She is a very happy girl, always smiling, has the cutest sense of humour and nothing else is really concerning me. But since I am a FTM, the rolling part is kind of worrying for me. I did mention it to the paediatrician at her 5 momth appointment but he wasn't that concerned since she was reaching her other milestones. I am thinking that maybe she hates rolling over? Could it be? She doesn't seem that bothered to roll! Maybe some one else is going through this as well?
