My earliest memory is of my Mum telling her friends that I was born with a smile on my face, that I rarely slept as a baby and that in fact whenever she or my Dad put their head in my room they would find me awake and smiling. I heard her say this over and over and like most things that are persistently repeated, I eventually believed it to be true. Is it any surprise that I grew into a happy adult, with sleep challenges? Happiness hasn’t always had a front row seat in my life.  It ran out on me when my husband and my Mum passed away.  But after the pain and the grief it bounced right back because by then it had become my natural mood.   I’m mostly a cheerful Charlie and I claim absolutely no credit for it at all.  It’s all my Mum’s doing. …
