My DD was exclusively breast fed until a couple of days ago when we added in a top up of formula on the paediatrician's recommendation, as she doesn't seem to be getting everything she needs from me - she suckled for hours if I let her, and always seems hungry, not sleeping much.
Today I've noticed that her breath stinks of sour milk. Could it be due to the formula? Reflux? Something else? I'd love to know if anyone else has had this.
We've got a routine check tomorrow anyway so will ask the paediatrician.
