DS is almost 5 mths and for a couple of months now has been waking at around 5am every day. He goes back to sleep only after I replace his dummy 4 or 5 times. By this stage dd is awake. He goes to bed at 6 and we start the day at around 6am.
Some background info:
He's usually fed once during the night around 1am. Sometimes I feed him at 4 as well and he still wakes at 5 so it's not hunger.
I don't think he's cold he still wakes when the house is heated.
There's no noise at that time of day.
His nappy is changed earlier in the night so it's not too wet.
Anyone have any suggestions on getting him to sleep past 5? I'm not against letting him cry for a few mins but I'm worried he won't go back to sleep at all.
I can't keep starting the day at 5! Help!
