Great advice, Anney! Both of my kids have found listening to CDs at bedtime really helpful for getting relaxed & ready to sleep. DD1 likes audiobooks but DD2 will opt for a combination of stories, guided meditations, and restful ambient music.

The other thing that has made a huge difference in this house was when I changed all the light bulbs in the living areas & bedrooms to the warm daylight colour, in a lower wattage. This seems to have helped everyone in the house get more & better sleep. We also adjusted the tv to be less bright and less blue.
