Since having Chicken Pox Charlie has been really funny about getting changed or having a bath, he wants to keep the spots covered up all the time which has been a bit of a challenge as they are everywhere!!  Today we found out the reason why though...

Charlie (after being to the loo) - HELP MUMMY I NEED TO PULL MY TROUSERS UP REALLY QUICKLY!!
Me - Why?
Charlie - I need to pull them up before Alex sees my spots. I am very worried about him
Me - Ok. But why are you worried about him?
Charlie - Because if Alex sees my spots then he will get spots too and he will be poorly and I will feel sad

Awwwwwwwwwwwwww!!!!
