so my nipple still have a huge (i dont know what to call it) crack. im using breast milk and lanolin. it starts to get bettah and then i feed and it cracks back open. i try to feed on the other side but sometimes hes still hungry and wants the other side. and plus since its on the side that has more milk i dont want to stop feeding him and loose the milk till it gets better. it also keeps opening up cos it sticks to my shirt or bra and opens back up. what can i do to help heal the process?
