When DS1 was v small my neighbour recommended some essential oils to help him sleep. Think she could hear him through the walls . Didn't help DS, but has worked a treat for DH and me, until now. We have run out of the stuff
It was geranium oil and something else. 2 parts of one to one of the other. For a baby it is a couple of drops in half a pint of hot water near but not under the cot. For grown ups it works in the bath.
Sorry to be so vague. Any clues?
