My lo is 15 wks old and was sleeping through till 7am but a few weeks ago (3 or 4) started waking at 5am. He used to disturb and drift back off. Could he now be hungry, tho sometimes he makes it till 6.30? would a dreamfeed help maybe? Is this a good age to start this or too late? Or could it be he's going to bed overtired as I read in another thread? He doesn't sleep for very long in the day, usually 30 mins at a go, and is very tired at bedtime, 7.30ish. Other days he seems to do a big catch-up. Or maybe I should just count myself lucky that he sleeps as well as he does and wait till he's older to sleep longer again. just worry he's not getting enough food and/or sleep.
