Having recently lost both grandfathers, my son (just five) has been full of Death Questions.
Best yet was, 'Does Father Christmas die?' Me: 'No because he's magic' Ds: Well, what about the one we saw at school? (which at least proves he knew it was just some unlucky daddy roped in by the PTA and not a chuckling chap just in from the North Pole!) Also enjoyed, 'Did Grandad fall over when he died?' (clearly been watching the wrong sort of videos).
My dd (2 and a half) has recently taken to waking up and announcing, as she stumbles out of the duvet, 'xx [ds] got a willy. Daddy got a willy. I not got a willy. Mummy not got a willy.' The other day, she added thoughtfully, 'But [ds'] willy hidden in his pants.' Would these be your waking thoughts on starting a brand new day???
