DD is 8 weeks and is EBF. She has a good latch despite a minor tongue tie which doesn't need snipping as she can roll her tongue out fine.
She suffers slightly with reflux and is on gaviscon and ranitidine. She has a bottle of expressed breast milk at bed time and throughout the day she goes on the boob.
Sometimes however she gets a little frustrated and is on and off the breast and crying/whimpering and my DP is getting angry with me saying that she's still hungry but isn't getting enough milk from me. He obviously sees that she drinks her bottle well at night and thinks she should be on bottles.
Also in regard to her reflux, DP thinks it will be settled if we were to put her on lactose free formula. I did suspect she may have a cows milk allergy and I tried cutting dairy out of my diet to see if it made a difference which it didn't and my gut instinct is that she doesn't have a cows milk allergy and the reflux is nothing to do with consuming dairy, plus she shows no signs of having cows milk allergy as our DS did only he was formula fed.
I'm babbling on a bit now but basically I've been called selfish for wanting to continue breastfeeding, please note that she's been weighed and she's growing perfectly along her centile line so she's obviously getting the nutrition she needs. DP has threatened to leave as he can't put up with seeing DD 'suffer'.
I personally feel strongly that she isn't suffering too much from reflux, but he's exaggerating. I'm with DD every day and she's with me every second and comes everywhere with me. I know my baby. I've also tried to tell him the benefits breast milk bas on our baby and how it can change too when baby is sick, which despite me googling it and showing him for proof is apparently 'bullshit' 
I guess I'm just looking for some support, sorry if this is long, didn't want to drip feed.
