3 month old having trouble latching to bottle and fighting bottle

Kat

Okay I seriously need some help or advice. My LO has always been fed by bottle because she had trouble latching on to me. She had been doing fine. But the last 2 months it's been a fight and she screams and cries because she gets frustrated because she can't latch. Once she latches she drinks like she's starving. But I always feed her as soon as I see hunger cues. Side note she has torticollis and is being treated for it and also has thrush that will absolutely not go away I've tried EVERYTHING. I know the thrush and torticollis can affect her latching, but it hadn't been bothering her before until recently.

Her thrush has been treated with 2 liquid nystatin and liquid Diflucan and gentian violet. None of it worked.

I have also treated myself with Diflucan for 4 days. All her bottles are sanitized and everything.

I'm stressed out and feel like a bad mom. I try so hard and do everything to help her and be calm. Idk what to do 😢
