@payanddomsmommy0916, thank u my Grandmother said it's normal n this bottle should be ok

My son drank from those but the classic ones. Those are really good bottles.

Hiccups are totally normal

I agree with @mommy2benntley. Try the preemie nipples if you haven't tried that yet. My son did the same thing and his nipple size was to big and it was coming out way to fast for him.

What kind of bottle it might give him to much air you can try switching bottles or try burping longer
