LO is 3 days old, think my milk is coming in (boobies are huge and swollen and hard) she has been feeding every 2-3 hours but since last feed (12 o clock) she has fed 3 times but just keeps throwing up afterwards. Really worried that she is not getting enough. She is fast asleep now though. Could it be something to do with milk coming in or that she is just being greedy and so throwing up?
