My 5 week old has been decreasing her feeding time. She used to fed for exactly 7 minutes. At first, I thought that she wasn't getting enough milk but her weight gain has been great. When I pump, I can fill 2 ozs in about 1 minute, so I am guessing that my milk comes down very fast. However, I am worried about her only feeding for 4 minutes every 3 and half hours. She has also gotten fussier at the breast. She will latch on for a little while then start fussing and wont latch on again. I am exclusively breast feeding her and am starting to wonder if i need to give her a bottle? Please help!
