My dd for the last 2 months has been waking between 5 - 6 am she goes to bed about 7ish and sometimes takes at least 1/2 to go off to sleep, but no matter what time she drops off she still wakes same time, but usually even more tired than normal. I'm not bothered by it as she's very good at staying in her room and playing til I get her, but she's shattered by the afternoon and grumpy. If we go in the car she is almost asleep which she never used to do so I know she needs the extra. I don't know if it coincides with the fact that she now is dry thru the night and so sometimes wakes for a wee and can't get back to sleep. I thought I could try waking her at 4.30 for a wee and try and break the cycle???
