My son is one month. ..this is the 2nd time he wakes up late trying to gasp for air & his mouth full if sticky like spit...anyone gone thru this what can it be? ?He's 3 weeks preemie & stayed in hospital nicu because his breathing wasn't stabled. .
My son does that because of his acid reflux
Try using the bulb syringe to suck some of the spit out of his mouth.
Acid reflux.
