Help! My 10 week old is a great nurser, but lately she has started to do this thing where she gets extremely upset when I switch breasts. No matter which breast I start on, she will eat really well off the first one and then halfway when I go to burp her (she gets some good burps out) she refuses to go back on the other breast. I have tried a range of times like switching at even 5 minutes and she still won’t go on the second breast. Which ever I start on, she will eat forever, but once I pull her off (at any point) to burp and switch, she gets really upset and won’t nurse again. Thoughts???
