My baby will turn 2 months in another 1 week. I am noticing some change in his feeding pattern. He feeds properly for around 15-20 min and after that he starts to feel uneasy while feeding. He gets irritated, It feels as if he is not getting enough milk while suckling. But I don't think that is the case, as when I squeeze, milk stream comes out nicely. His general feed time is 30-40 min per feed from 1 breast. please advise
