5 week old eating disaster !!

I’m writing this in hopes that someone had a similar experience and can share some feedback.

I have a 5 week old she’s been breastfeed since day 1 but we’ve also supplement with sensitive similac from day 1 as well to ensure that she was getting enough while my milk supply came in.

Initially she drank and bottle fed just fine. Up until about week 3

The only change that I can think of is that we started giving her the bottle more per the advice of the lactation consultant because I was still trying to build my supply by pumping more and it also gave dad a chance to “help” with feedings 🤨

For the last week and a half maybe two feedings have turned into an absolute disaster

On the breast she’ll lose the latch then lose her mind. I’m talking full on screaming as if she’s in pain. If she gets the latch back she’s still drinking and fussing pulling her head back, flailing her arms pushing and pulling the breast away from her but still trying to get it. It’s also not a matter of low milk supply because I have soooo much milk that it’s painful. It literally just shoots out at times.

At first I thought maybe it’s something im eating, however she does almost the same with the bottle and formula. She’ll get upset push it away start screaming and crying. So feedings that used to last a couple mins turn into an hour spectacle.

(She also refuses to take the bottle from me now and is always opening her mouth rooting around looking for my nipple)

She’ll literally wiggle and launch herself down until she’s in front of my nipple and try to get it.

Which makes me so sad because clearly she wants it and needs it.

I’m not sure if it’s nipple bottle confusion, I’m not sure if she’s in pain some how. She does have build up on her tongue which the pediatrician told me two weeks ago was milk and can be wiped off with gauze. But I guess the buildup could also be thrush ? I have another appointment with the pediatrician Monday so I’m PRAYING that he has a solution.

7 or 8 out 10 times she’s screaming and unhappy during feedings which wasn’t the case a few weeks ago.

I’m also making an appointment with a speech pathologist i believe for a possible tongue tie.

This is particularly stressful for me because s/o works 7pm-6am and usually sleeps until 2 pm so I’m basically in charge of all except 1 feeding which is every 2-3 hours.

Any and all advice thoughts welcome ☹️
