he has been doing it on and off for about 2 weeks...some mornings he sleeps through and other mornings 4.20am on the dot...my parents are staying with us at the moment and he has had a cold this week which may have something to do with it...His bed time routine is always the same....we have tried controlled crying and he does not respond to that he just gets himself so worked up so the only way to get him to sleep longer is to pick him up to settle him down, wait 15mins or so until he is in a deep sleep then put him down......Not ideal but seems to be the only way he will keep sleeping..
Thanks for the information. Having a cold and new people in the household are enough to change his routine, plus it is getting lighter earlier in the mornings.
A few things to try: Make sure he is put down for naps and bedtime awake not already asleep, so when he wakes up and someone is not right there he is not scared ; Try adjusting nap times a bit so he may be more (but not over-)tired at bedtime. ; Try feeding a bit more solids 1-2 hrs before bedtime.
Hope this helps, please post more questions as you have them, Best,
