I schedule to feed my 2 months baby every 2 hours for 20 minutes (one side for each session) from previous feed starting time.. But my lo pee 2 or 3 times and try to roll over and start crying within 1.5 hours. My query is this normal because her energy drops by roll over and pee or my milk supply is insufficient or my feeding time or only one breast at single session could be reason for her hunger cry???
