Tummy time help?

St

Will ask pediatrician at her appointment on Tuesday, but my LO turned two months today. She hates tummy time so much that she taught herself to roll belly to back yesterday 🤦🏻‍♀️

She will hold herself up well on our chests and on Boppy, but when on flat surfaces will lift for a few seconds and then lay flat crying and sucking her hand.

Does she need to do tummy time flat? And if so...how do I keep her from rolling over the second I lay her belly down?
