Today i fed baby 1 hour 36 minutes including time he sleeps, after i latch he drinks , he  pushes me, and cries, again i latch so this continued. Milk was leaking from side of mouth . Does this happen usually?? After this much time he gets up after 45 minutes. But now after few minutes at breast he cries and he looks very hungry . He tries to suck again. Again cries. So it looked he was very hungry but i dint have enough milk. Had to formula milk with no resort.
