I'm so desperate for help. My almost-4-month-old daughter has started arching her back and screaming during her afternoon and evening feedings. I have tried varying positions (cradle, lying down, her sitting up), moving to another room, burping, rocking, and walking to no avail. Last night I finally pumped a bottle and she guzzled it down hungrily and went to sleep.
I'm not sure if any of these details matter:
* She has been sleeping through the night (8 PM to 6 AM) for a few weeks
* She has been exclusively BF with very occasional pumped bottles (once every few weeks)
* I think I have very quick letdown (sometimes milk spurts out in a jet) but this doesn't seem to bother her in the AM feedings
* She seems healthy and she's growing longer and getting plump
However, despite these good signs (e.g. growth, sleep), the crying at feedings is making me feel rejected by my daughter and I'm totally demoralized. I thought breastfeeding was supposed to be a beautiful bonding experience, but now so many feedings end in tears for one or both of us. Please, please, please if anyone has ideas or encouragement for me, I would be so grateful.
