Hi Emma! I have had a lot of trouble sleeping at night since I was about 4 months pregnant... It got worse once bubs was born but is getting better now. My best way to get to sleep is something I made up myself...

I lay in bed with my eyes closed and concentrate on one point somewhere in the room (ie the fire alarm) while counting from 101 upwards... If I just count from 1 upwards it doesn't seem to work...maybe because I can do that without concentrating as much but I find if I keep concentrating on the numbers and that one point then I rarely get past 150 because I'm asleep. If I loose track or loose concentration then I just pick a number and keep going...

It has worked wonders for me. Maybe it might work for you too... Let me know how you go if you do try it.
