I gave my daughter 6 oz of formula and a jar of baby food but it all depends on appetite give her baby food then let her take as much formula ad it takes for her to get full.
He usally drinks 6oz but he sometimes wants more like a hour in half later or sometimes 2 it depends. so know iv been given him a couple spoons of vegie a couple of fruit and a couple spoons of rice cereal and a 4oz bottle but idk if that's to much
Every baby is different. If you are concerned I suggest regular weigh in's every couple of weeks to check weight gain. As long as baby is happy I wouldn't worry. They will be sick if they have had too much and will cry if not enough so they are good at regulating amounts themselves.
I agree they will let u know that is what my little girl took at that age sometimes she didn't take it all sometimes she did. But go with ur feelings. You know what is best for ur baby let him decide he will tell u.
