My baby rolled over !!... And then stopped

My son rolled over last week, back to front and did belly to back previously. Not a master of either but can usually do both, and would try to add soon as we put him down- loved his play mat.

This week, no interest at all. It's been a few days since he rolled over and is crying when we put him down. He not even trying to roll be which is odd for him. He is teething, but idk if that could have anything to do with it.

Any advise?? Been 8 years since my first so I forgot everything 🤷‍♀️
