Insomnia help !!!

[Mummybear15]

Hi
I have a 4 month old baba he is in a really good routine goes to bed around 7:30 sleeps till 6 has a bottle and goes back asleep till about 8

But once he's gone to bed I can't seem to sleep that's why am up now posting comments lol

I don't want to take any sleeping pills as I'm scared of not waking up to babs

Iv tried warm milk, Horlicks ect
I feel as if my mind is in overtime soon as I try to sleep any ideas ?

Counting backwards from a high number or naming countries alphabetically sometimes helps me. I read once that it is the 'right' sort of brain activity to assist winding down.
