4.5mth old rolling onto tummy asleep

[loopyloutoo]

My 4.5 month old has just learnt how to roll and they keep rolling onto their tummy whilst asleep. I haven't seen them roll back from tummy to back whilst awake yet so I'm freaking out they won't be able to breathe if on tummy? They're in a next to me, nothing in the cot and wearing a 1 tog sleeping bag only! Help!

They should have good enough head control to rise their head and cry or move their head so they can still breathe if they’re able to roll. They’ll either cry for help or get themselves out of an awkward position.
