my first child it was feeding, I tried and tried to get him to latch and he wouldn't (he was a premie and the nicu gave him bottles)... with my second it was both pregnancy and sleeping
feeding. my daughter spontaneously stopped latching to my breast at 2 weeks old (I'm pretty sure the Binkie had something to do with it ) so I continued to pump for 2 weeks and bottle feed however that got to be to much to handle so I had to switch to formula. it broke my heart but as long as she's getting fed and growing I'm happy.
