My DS has had a pretty strict routine with bedtime since he was 9weeks. Bath at 6 and bed by 7. He has never been amazing sleeper but we did go through a short phase of him going 7-7. He has now started waking earlier again (5am - urghhh!) and this time I can't blame the sunrise.
My childminder has suggested that 7pm is a early bedtime and that we should try pushing it later.
What time does your little'un bed down?
