He turns 4 months old today and I'm suddenly having a hard time getting him to nurse. He's crying and refusing the breast, yet when I left last night for 2 hours he readily took a bottle I pumped. Now its during the night. He usually nurses pretty often. He nursed once without issue. But the 2nd time he woke up hes full on refusing to eat to the point he went back to sleep. This is very unlike him. I'm super engorged now...should I pump? I dont want to discourage nursing, he's always been so good at it. Just a little more distracted lately.
