Confused with my newborn UPDATE

He’ll be one month on Wednesday I just upped him to 4oz (formula fed) every 3 hours I know it’s a lot but he is always hungry idk what to do! He’s always hungry always spitting up like alll the time

I’m feeling overwhelmed I feel like his belly hurts or it Hurts him when he spits up

I burp him lots give him a paci even tho he hates them it’s just so much work timing his feedings and making him wait what am I doing wrong please help suggestios?!

He has an appt coming up I will tell his dr just wanted moms opinion

Update

A lot are saying 4 oz is too much trust me I’ve tried doing 2 oz and then 2 later but no he wants more eating the 2 oz does nothing for him. I can’t stop feeding him he will literally cry and cry for more I comfort him try giving him the paci for sucking but that doesn’t work.
