In cool / cold weather you can use a baby sleeping bag / grow bag.
One of ours starting rolling over much younger than babies normally do. He would put on a towel on his stomach to dry his back etc. quickly and he rolled himself back onto his back almost immediately. When he was old enough to have tummy time he hated it and would scream non stop until he was put back onto his back. We needed to cover our ears he was so loud.
You will probably find that in the waem / hot weather even if you have airconditioning they tend to roll around more as the mattress holds baby’s body heat and baby moves onto a cool spot during sleep. You may put baby one end of the cot, check later and baby be the opposite end or laying across the cot instead of lengthwise.
