Wow, they don’t believe in silent reflux??? Think you need to change your GP.
our boy was the same in that he would scream all day (he had colic too) especially around feeds and would wake up from naps upset (I think this was due to reflux coming up and waking him and hurting).
I had lots of tearful calls to the HV and GP and got nowhere for ages, tried gaviscon but it made him constipated.
the best thing was omeprazole, takes about a month to work but a god send, it reduces the acid in their stomach so what comes up doesn’t hurt anymore. Please please push for omeprazole , don’t let them fob you off with gaviscon any longer. I only discovered it because one HV mentioned it when I called, she said it pretty much always works when it’s reflux.
once we started weaning at 5 months we came off omeprazole at 7 months and he is such a happy baby now, so he’s grown out of it. Weaning really helps with reflux.
our boy also slept well at night and still does, he used to wake once for a feed but since 4 months has slept through. Often babies with reflux don’t sleep well at night but it’s not always the case, we found that if we held him upright for 30 mins after his bedtime bottle and then put him down it helped. We think he was exhausted from all the crying and that’s why he slept so well at night! But it actually helped him create good sleep habits, he’s 8 months now and still sleeps through every night.
good luck and don’t let them fob you off! I asked my GP for omeprazole and he was happy to prescribe it, but he didn’t offer it, I had to ask. I don’t know if it’s expensive so they try to avoid giving it unless you ask? Xx
