Is anyone’s baby still eating every 2hrs?

I’m having a really hard time with my baby who’s almost a month old, not settling due to reflux and maybe colic! He’s got the worst nappy rash and is constantly pooing. The poo’s seem normal in consistency, and he’s still feeding but has trapped gas and wind!etc. We were using infacol but saw online it can make reflux worse so instantly stopped. I’m trying to make a doctors appointment now to speak about the reflux. But due to all the combined issues, his feed times come round quickly and he’s practically starving every 2hrs and sometimes 1.5hrs. Maybe because he poo’s and pee’s so often and digests it quickly. Again, he doesn’t have diarrhoea. It’s all just exhausting as im done keeping in straight after feeds due to reflux, nappy changes and just soothing him, his next feel is due. And even I don’t wake him, he wakes up screaming for food. Literally goes 0 - 100 in 2secs. I’ve tried to do 3hr windows but it isn’t working for him. He basically has so many symptoms but because he’s feeding regularly and has wet nappies I don’t know what it is. Just exhausted! He is formula fed and I’ve changed from cow and gate to aptamil to now Kendamil. I don’t think he has a cow protein allergy. Any help would be appreciated. From a very exhausted, worried FTM!
