My Ds is just four and has been waking up in the night and early in the morning. I'm wondering if he's going to bed too early. He was a good sleeper until 3.5 but now he wakes up in the night and comes into our bed wanting 'a cuddle'. We take him back to his bed and he falls asleep quite happily again. This sometimes happens two or three times a night. He's also started waking earlier - 5.30 this morning. He goes to bed at 7.30. Is this too early? Any idea how I can stop the night time wanderings?
