We are very lucky in that after a difficult first few months, DD now sleeps from 7pm through the night (usually). She went through, blissfully, to 7.15am or so for a while, but has been waking earlier, and earlier, and earlier over the last few weeks. Today it was 5.55am, and I can just see it continuing to get worse! The earlier wakings coincided with her naps at nursery (I work 3 days / week) taking a nosedive as her 'key' person went on holidays for two weeks, 4 weeks ago, and they have never really recovered; sometimes she only manages an hour total over the course of the day.
When she is at home with me she goes back to sleep about 8am-ish - she is still asleep now! Are long early morning naps at home perpetuating this, or should I be letting her catch up on the sleep she misses on her nursery days? I'm going to talk to the nursery about what we can do to help her nap there, but if anyone has any advice about structuring her sleep to help the early waking it would be greatly appreciated
