Bottle feeding help !

Brittany • 1 👼🏻 & pregnant with my rainbow boy 🌈 🥰💙

So my little man is 9 days old , and has a baddddd tongue tie . We are waiting for it to be clipped , until then I’m pumping and feeding .

The problem is, the slow nipples are too slow, he doesn’t drink anything within a 15 minute time span. But the medium flow , are way too fast for him .

He gulps it down even though I stop to burp him every ounce , and ends up having hiccups every time he’s done eating

What should I do ? Are the hiccups normal ?
