I have a one month old baby. Sometimes when he's in his basket (having had milk, fresh nappy, all the usual things to keep him happy) he does these little bursts of crying that last for five seconds or less. Just enough time for me to get out of the chair and head over to the basket, only by the time I get there he's stopped and looks fast asleep. I go back and sit down and a few minutes later he does the same thing again! Is this normal? Does it mean he wants more milk or something? It's v confusing.
