any body elses babies randomly wake during the night and cry once or twice but not actually awake while doing it.... my son woke about a month ago about 5am (uk time) like proper crying but werent awake until i changed his nappy which woke him gentally ... i thought this was a one off as he didnt do it again until this week ....for the last few days he has cried only once or twice while asleep which has woken me up but its been around the same time between 530 and 6am ....confused
