My LO is 6months old and has the flu since Saturday. For the past 3 days, he refuses to nurse. He needs fluids, so I offered a bottle and he'll take it, but screams when I offer the breast. I've tried squirting milk in his mouth to try to intice him to nurse. It's no good. He won't go for it. He's very congested. I don't know if nursing is too much for him right now or why he won't nurse. I want to be able to nurse when he's back to feeling better. Any advice?
