Baby sleeping on front-help!

Sarah • Proud mum to baby boy born April 2019 through IVF 🥰

Tonight I’ve moved my 7 month old baby boy to his own cot in his own room. I’m currently sleeping in his room to keep an eye on him he’s been up every half an hour constantly rolling to his front. He’s sleeping and seems comfortable but if I turn him over he cries and rolls back to front. Do I leave him like this? I can’t stay awake all night to keep turning him over. X
