Hi there

I don't know if it made a difference but I basically tried to show my daughter that daytime = interesting and night-time = boring, might as well sleep.

So during the day, I would have her in the living room/kitchen with me where there is a bit of noise, people's voices and stuff to look at etc. etc. She would still sleep when she wanted to sleep but there were things for her to look at and listen to as well. So by comparison, night was quiet, people didn't talk and there wasn't much going on. I also had her sleep in her bassinette in the living room - not so much to teach her the difference between night and day but more because I couldn't bear her being in a different room to me. By accident, I think she worked out the night/day stuff pretty quickly and she'll also sleep pretty much through anything which is handy!
