[Sundae]

Nothing worked for me re nightmares.
Although Limey can attest that I'm fine once woken up.

Mum used to be able to calm my night-fears though.
I hear her voice even now when I'm working myself up into a state (aka two o'clock in the morning thoughts).
"Sssh now, it's okay. Can you do anything about it right now? I mean right this minute? No. So we'll deal with it in the morning. If you lie still and rest it will give you strength."

As a Teaching Assistant my magic bag held bubbles, wet-wipes, patterned tissues (because even a snotty child wants to wipe their nose on a puppy) a whistle and mini-binoculars.
My priorities were different than those of a parent, but the kit worked for the role.
