My little one is 12 weeks old now, and has been doing great nursing. We have had a rocky road but things seem to be going well until this morning. He ate fine when he got up at 4 am for his night time feeding but then this morning he wouldn't nurse. Every time I tried he would scream and not latch at all. Finally at 9:30 I just made him a bottle which he took.
Any ideas what may be wrong?
