Anxious parents out there: At what age did you stop checking your sleeping baby to check they’re still breathing?

I know anxiety among new parents is not uncommon, and especially when you have a new very young baby; but I wonder when will I grow out of this annoying anxiety I have to keep checking on the baby every now and then when she’s asleep?

This is my first child so I hope I can learn to relax soon.

Looking forward to any advice out there- Thanks in advance
