I have recently slipped 3 discs in my back and it is incredibly difficult for me to nurse my LO- I pump during the day and nurse him at night lying down- which is still hard to do with my pain. I would like to start supplementing in order to ween him as I have 2 surgeries pending. Should I night ween him first? He is eating 3 solids a day and takes about 12 oz of BM during the day and then nuses all night long on demand. Is it ok to night ween him at this point?
