Hi, my first baby is 5 weeks old, and one of my nipples is very badly cracked, so I'm expressing from that side as latch on is very painful, and to give it chance to heal. This is working, but since I started that boob is always hard and full, and I don't know if I should be draining it, or just expressing a little to avoid the engorging?? My boy still seems to be getting enough, and is happy, so I'm not worried about him - just me, as I don't want it to turn into mastitis etc. Help! .... thanks.
