My baby girl is about 2.5 months old and is a breastfed baby. She has never had a problem with latching or anything like that, but starting yesterday she suddenly changed from her normal 2 hr feeding schedule. This would be perfectly fine with me except that she is giving me all of her hungry signals, but screams when I try to put her on the breast. She is still happy and smiling and has no fever. She is a bit more fussy than normal and it's worse today than yesterday. She is still getting enough food and I am calling her doctor, but has anyone else experienced this?
