I finally got my LO on the breasts. She never nurse more than 7 minutes on the left side and sometime cries and refuses it, but she would nurse more than 15 minutes on the right without any problem almost every time. She seems more willing to take the left breast if I offer it first. I was told to alternate breasts each feeding, does it matter if I offer the left breast first every time ? Is this going to cause my breasts/or milk supply to be uneven ?
