Is it ok to let a almost 7 month old sleep on his belly?

Be
My baby will be 7 months March 8. He usually sleeps on his side but tonight I have already flipped him over three times in 2.5 hours. I'm disturbing him every time but he goes right back to sleep. Can I let him stay on his belly at least until I go to bed? I just want him to be comfy. He sleeps in his crib. No blankets except his wearable one. Nothing is the crib with him either.
