newborn

Ashley
Did anyone else newborns have hiccups after feeding? Went to my sons first doc apt on Monday and come to find out we weren't feeding him enough so we are now feeding 2oz. 
And he was still getting hiccups but now when we feed him 2oz he doesn't have as much but still does have them!
Do you guys think something is wrong? 
Ppl say it could mean he is growing, getting to much air, or overfeeding😩 I don't know what if is PLS RESOND
