DD1 (7.5) has just been into the toilet and said
"Mummy, there is something in a box on the floor and it says TEMPAX ( ) what is it for?"
I responded with "um, um, well darling it's something that you don't really need to know about too much until you are a bigger irl but basically it's something mummy needs to use sometimes"
She insisted that I tell her more - so I did, but very carefully and gently without wanting to make her afraid. She seemed very interested and not at all worried.
So there, my first Mum and Big Girl chat done and dusted. Awwwwww! - what happened to my little baby girl?
