2 questions for you mommies!
1. my son is 4 months old and is now rolling from back to tummy and so on. he rolls onto his tummy in his sleep. from what I've noticed usually with his head to the side. am I okay to leave him or will he go face down? I'm worrying myself all night while checking on him.

2. I do not have a/c in my car. it's gonna take a lot to get it fixed. how far down can I roll the windows down without taking his breath away?

TIA!!!
