I already posted this in the breastfeeding support group dissusion forum with no responses, so I thought I'd try here. My baby is a little over 3 months old. I work full time so she is bottle fed expressed milk during the day but I nurse her in the mornings/nights and weekends. I have not had any issues...up until now. This past weekend, she refused to take my breast. I tried and tried and the more I tried, the more upset she got. I thought maybe something was wrong with my milk but then I pumped and gave her a bottle and she drank that like she had never eaten before. This happened all day. The last few days, everything has been fine and she nursed from me with no problems. Yesterday she started doing it again. She would nurse for a few seconds then start whining and pull away. The more I tried, the more upset she got. To the point of she would start crying as soon as I put her in a cradle hold. I knew she was hungry as it had been several hours since she ate. My mom seems to think she might break a tooth soon since she's very drooly and her nose has been runny. But no fever and she's only 15 weeks. Isn't that too young to be breaking a tooth? Or, is it possible that she's just preferring the bottle now since she's bottlefed all day 5 days a week? But why no problems sometimes and diffulty other days? I'm a bit upset about this. I really wanted to nurse her for a minimum of 6 months, preferrably a year. Has this happened to anyone?
