My 2 week old is eating every 2 hours now and everytime i give him his bottle he starts gulping it down which makes me think he’s sucking in way more air than he needs too. He tends to do it about halfway through his feeding and then once he’s tired he will slow down.

Should i change the nipple out on the bottle? (He’s using a size 1 now with the avent bottles)

Or could he just be extremely hungry and need more formula while feeding even though he seems satisfied?

I’m a first time mom without a lot of help so i want to make sure it’s not hurting him
