3 days ago I had no milk supply so I was a little disappointed that I had to put my son on formula but I was trying to get him on the breast (problems latching but now fine) I woke up this morning and my breast were so sore and felt like the first few days after the milk comes in is this normal for it to come back like this. We are now on the breast as of this morning yay us
