Acid reflux?

Hannah

My baby is 8 weeks old, at first i thought he was just a fussy baby who had hit his peak but recently hes got a LOT worse. He seems uncomfortable all the time, espcially after eating (hes formula fed and has Cow and Gate stage 1 milk - weve been told by the HV not to change it or put him on any of the different types such as comfort etc) for the first maybe 4-6 weeks he woukd projectile vomit after a bottle however it was put down to him drinking too fast so we now do paced feeding, he arches his back when he cries, he will make gulping noises even when he's not drinking and often gets the hiccups, he pulls faces as if he's eaten something disgusting and he just seems overall uncomfortable. We have also found that he will randomly spit up even hours after his feed. His poo seems normal (I've google loads of photos of poo my partner thinks I'm crazy😂) however recently its really really smelly and it no longer is seedy! He also HATES being lay down, whether that be in the bath or lay down for a nap (which have reduced dramatically during the day (he won't sleep for more than 20 mins at a time during the day - he maybe gets 10-12hrs sleep a day with the majority of it being on a night!)

I took a video of him crying to show the doctor as to me that's a really uncomfortable cry and this was during a feed, hes literally screaming, holding his breath, turning red, tensing him 🥺😔

Any advice would be great? Is it reflux? Or do i just have a unhappy baby?
