Lincoln's been waking up crying during the night for a few weeks now. He would be on boobies a lot and suddenly he starts to cry and kicks about. He cries for 20-30 minutes then back to sleep. He's awake when he cries so it's not sleep crying . I don't know why,some nights he cries a lot. The only reason i can think of is he;s hungry coz at the nursery he eats and drinks a lot and he doesn;t drink or eats much dinner at home and my supply's been quite low coz he has cow's milk at the nursery... what do you think it could be ?
