My son is ready to be 4 weeks and I’m starting to start my stockpile for work . I’m a ftm and not sure how much he should be drinking . I’ve tried to give him 2.5 oz he still gives off hunger signs . Should I go to 3.5.? What is too much .? Should I just let him drink until he stops himself ? When I nurse him he stays on for 10 mins then refuse and wants to eat again 30-45 mins later . Is that normal ? I just feel as though I’m ALWAYS feeding my son lol and is it common for breastfeed babies to spit up .? It’s never a lot to cause concern but I thought the only is something formula fed babies do
