Hi, my LO is 1 week 3 days old. I feed him by latching and formula, sometime I express out the breastmilk. I am wondering why everytime I latch him he seem to not feeling full and keep wanting to drink again after awhile. Sometime I latch him, he fall asleep or push the breast away so I thought he had enough and I put him on bed. But about 10 mins he start to be cranky again and want to drink milk, this last for 1 hr plus and I have no choice but to give him formula. Any mummies experience this?
