Overfeeding

Royal

I’m worried that i could be overfeeding my LO. He constantly eats only at night time. I have to give him the bottle every 30/45 mins. He eats atleast 7/8 ounces within two hours. But he’s throwing some of it up smh. He just turned 4 weeks is weighing 8pds 13 oz! I try to console him in anyway possible and nothing works but the bottle!! I tried talking to my doctor and he basically said if he wants to eat feed him as long as he is not throwing up. My LO throws up and then crys for milk again. At this point i don’t know what to do! Any advice?
