So I feel like I have failed my son I was only able to keep my milk.in for 3 weeks cause I was told not to force my son to latch when he fought me cause he was burning calories and they didn't want that cause that would make him lose weight so I pumped religiously to bottle feed him my milk and pumping didn't keep my milk in and I even tried lactation tea to bring my milk back and no luck so now he has to be on formula full time and that's the one thing I didn't want :(
