DS2 is 7.5mths old and has started rolling over in his sleep onto his tummy. I can tell when this has happened by the noise his breathing makes on the monitor. He doesn't roll back though and I'm wondering whether I should go in and roll him back onto his back or just let him sleep on his tummy. He hasn't cried out while on his tummy at night (though he does cry on his tummy during the day!). He just wriggles around a bit until he falls back asleep. He hasn't worked out how to get to a sitting position yet.
Do you think I should roll him back or just leave him to it unless he cries? Is he safe on his tummy at this age?
