My baby is just over a week old and has started spitting up a lot in the past day or two. I googled stuff and it said it can be from over feeding or her being too full but she used to eat (i breastfeed) for 30+ min at a time. Now she will eat for 5-10 and seem done like she wants nothing to do with the nipple and has been spitting up fountains of milk. Is this normal? Also after she spits up everything I’ve fed her do I feed her again? She has to still be hungry right
