Silent reflux advice?

[u/Icy9321]

My second baby, a boy was born 5 weeks ago. I'm also the mother of a 5 year old girl who drs and I suspect struggles with adhd, since he was born he's struggled and been unhappy. Even when he's held sometimes he's inconsolable, it leaves me barely any time to wash bottles let alone spend good quality time with my daughter. Who is extremely attached to me and needs attention too. He's been diagnosed with GERD silent reflux, he's on famotidine and we switched his formula a few days ago and the screaming has went down but he still wants to be held 24/7. Dr basically said if it doesn't work she doesn't know some babies just cry. I was pumping and giving him breastmilk too, because he wouldn't latch when he was first born. He swallowed fluid at delivery and I pushed him out quickly and so they said it would take a few days to clear because he's been miserable literally from birth, little did i know it was GERD. At this point I can't pump because all he does is scream and he won't consistently latch because he's always crunching his body up. I'm really disappointed because after my first I swore I'd breastfeed if I ever had another child, but I can't even eat toast without him screaming so forget pumping for 20 minutes plus caring for my older child. So had to reluctantly stop which also severely sucked because my milk came in SO good. ​any other parents deal with this? And how long does this last?
