Hot milk & honey works a treat. My kids love it when they can't sleep and it works wonders. It's been proven too.
oh yeah i totally forgot this one! i LOVE it! my Oma used to make it for me and my Oma told me how her papa used to make it for her! it sooo works, i have always struggled to go to bed early...ah yes, even now it is almost midnight and i am still up lol!

got milk, where's the honey?
