My daughter was 2 a couple of months back. For 6 months or so she has routinely slept through the night, often sleeping in as late as 8.45am!
Now all of a sudden she has started waking at 6am and refusing to go back to sleep.
Anyone experienced the same thing? No idea whats causing it but it's such a long day when it starts at 6am, and she is needing her nap about 10am!
