10 week old with CMPA feeding less after vaccinations, any advice?

[LeoSun11]

I don’t know what to do, my 10 week old baby has CMPA. She only ever drinks between 2.5/3oz every 2.5/3 hours. She had vaccinations on Monday & since then has gradually declined with feeding. She has gone from 23oz (which was a struggle to even get her to this amount daily) to 10oz. She has only drank 10oz from 2am this morning until 3pm now

Any advice? I’ve tried to give her little and often but she is just getting pissed off when I’m trying. Last night she went 5 hours with only 1oz then kicked off because how hungry she was but still only took 2.5oz :( the whole 10 weeks of her life have been hell on earth & im really struggling

I’ve tried different positions different feeders etc all the usual tricks but nothing works to get this baby to feed normally everyday is an absolute dread and challenge, I feel nothing I do is right. She constantly cries & it’s so unenjoyable I never imagined when my little girl was born I’d hate it as much as I hate this period right now

No help but wanted to bump this thread in the hope of someone knowledge seeing it

It must be so difficult. Can I ask which milk she’s on?

She went from nutramigen to aptamil pepti 1, it’s always a fight to get any bottle into her. She’s been like that from birth. Don’t know what to do anymore tbh, she’s been checked for a tongue tie which she doesn’t have. Checked for oral dysfunction, she doesn’t have. Swapped her bottles and teats numerous times it’s so debilitating. I’ve got a 2 year old son who’s suffering too, it’s taking me 45 mins - 1 hour to get a bottle into her. There’s times she will take the whole bottle within 20 minutes so I can’t understand why she chooses not to take the bottle.

ive tried stretching her out longer between feeds too so see if that makes a difference but still the same issues I’m at a loss
