This morning I did something that I feel may have been a big no-no. I gave my 3 week old son formula out of a bottle. I've posted in here a couple times and I have been trying really hard to breast feed. Some days it goes well and others it goes horribly. We finally (kind of) got the latch down, but now he refuses my right breast. He screams, kicks, and basically acts like I am hurting him anytime that I try to feed him on that side. I'm continuing to offer him that breast and trying to get him to latch on to it (he will take it in his mouth and spit it out and I'll put it back in and he'll spit it back out) but so far I haven't had too much luck so mostly I pump that breast while he's eating from the left side. He didn't do this a couple of days ago. I've been giving him my left breast when I finally give up on getting him to take my right breast and now my left breast hurts really, really bad. I guess this morning I just really felt like I needed a break and couldn't pump because my LO was screaming where he had just woke up so I broke down and gave him a bottle of formula. Will this completely disrupt my supply? Is there any recommendations on how I can keep my left breast from hurting so much and what can I do to get him to accept the right breast? Any information I can get will really help.
