My 12 week old baby is sleeping through the night from 7pm to 7am. She started to sleep through at around 8 weeks and I got a very bad case of mastitis because I didn't wake up to feed her. It took 2 weeks to get rid of it and I was in a lot of pain. I started waking her to feed so I wouldn't get mastitis again but this last week I've let her sleep through and I'm getting up through the night to express. How do I get my breasts used to not feeding through the night. I'm finding it hard to get back to sleep after getting up to express and she is not sleeping a lot through the day so I don't ever get a chance to sleep more during the day to catch up on sleep. I don't want to get mastitis again. How do I drop the night expressing? Seems crazy that my baby is getting a good night sleep, but I'm not. Any advice would be greatly appreciated. Thanks
