I think my little girl had abit of reflux so giving her infant gaviscon and she's so much better today. She's been so unsettled, didn't like lying down, arching her back when crying like in pain, alot of hiccups and sick ups. If in doubt go drs and get some of the infant gaviscon and see if it helps. Don't give the full dose tho just start off small doses and see if it helps. I know it can cause constipation.
It is more than likely reflux expecially if little one seems in discomfort, best to speak to a HV, you can go to a local baby clinic and see them there. When it comes to telling the difference between reflux/spit up and sick, when a baby is sick it's projectile and covers a large area or even up walls. My son has CMPA and had horrendous reflux x
My little one has been same I spoke to HV she said as long as they aren’t projectile vomiting and bringing up all their feed and haven’t got a temperature, not going off food then they probably won’t be poorly. I think my little boy has reflux though as he is fussy and being more sicky but it’s so hard to know what to do for best isn’t it! I’m trying to make sure he’s winded better and if no improvement in next few days I will take him to drs for some advice xx
