DC1 is five weeks old (born via ELCS at 38 weeks for maternal health reasons). I'm not sure what's relevant, so will try and cover everything! He was 8.5 lbs at birth, and 10.5 lbs at 4 weeks. He's bottle-fed as I couldn't produce anywhere near enough milk - very upsetting, but it is what it is, and I couldn't express anywhere near enough to keep any kind of supplementation, though I tried.
Since two weeks, he's been screaming a lot after meals in addition to the regular strained, pained faces when processing. MIL stayed for two weeks, and thought he was in pain a lot, but it was normal. When we saw the HV at 4 weeks (first appointment she could attend since birth!), she saw him in action feeding and screaming and was quite alarmed and said 'reflux, see GP'. GP saw us that that and, without examining baby at all, and based on us describing his behaviour, prescribed infant Gaviscon. We tried it that night, into the next day and it was awful - even more screaming and obvious pain, so we stopped.
Where I'm at now is trying to work out whether his screaming and crying is 'normal', and the HV overreacted, or whether we need to push for better treatment. This morning is typical example of how our days go. Fed at 8am, held him upright till 8.45am. Had to briefly put him down to give a dog medication (time sensitive, and it should have been given at 8.30), during which time he threw up most / all of his meal. Spent 30 minutes cleaning and changing him, changing bedding, etc. Then he's hungry again. Feed him and hold till 11am as screaming throughout, and hiccuping at various points. Wonder if he's hungry so, as bottle ran out, have to run to get a new one, which he then doesn't really want, but just wants to be held. Eventually put him down, and he leaks milk (more than posseting), but basically settles and is now asleep.
Basically, if he's not asleep, he's feeding or screaming, and very rarely awake and not agitated or in pain. Is this normal? If it is, that's fine, but I just want to make sure we're not letting him down by not pursuing things with the GP (though we'd probably ask for a doctor who will actually examine him!) / asking for a referral.
