For the past week, my daughter who is now 10 weeks old has been pulling off the breast about 20 seconds after I try and feed her. I then try again and the same thing happens. After quite a few attempts of trying she begins to get quite upset and eventually she will start screaming, kicking her legs and arching her back. I thought it could be related to my letdown so I have tried to feed her lying down, leaning backwards or sitting her upright but she still pulls off and starts screaming after several tries. I must be feeding her enough as she has adequate wet nappies. However feeding is becoming an unpleasant experience for the both of us, therefore can anyone offer any help and advice?
