So I have exclusively BF Kendra up until now, 4 months. I have a derby to go to this weekend and I will have someone watch her for about 5 hours. I tried a bottle yesterday with breast milk and it seems she is having difficulties with the nipple. Any suggestions on what worked for you?? I used to drop in style bottle. I have a week to get her ready for this... I am so nervous to leave her this long!!
