Mine just won't barely nurse! And I'm in the middle of my cycle so I know I have milk. He will nurse 4 times a day tops, for like ten minutes. I tried to force him to eat more yesterday and he actually spit up, which he usually only does after overeating. But he had only nursed for like 10-15 mins! Yesterday he bit me, which he usually doesn't do unless my supply is super low or he is teething. He has solids twice a day. Nurses 4-5 times daily. Although it is looking more like 4 is the norm now...
