I popped into Wilko yesterday to stock up on craft bits for 4 year old DS. I grabbed him a 50p roll of masking tape as he likes it for making models and I have to keep getting the tool box out to find it.
He is DELIGHTED. He has spent the last half an hour thanking me profusely. I am the best Mummy in the world and may borrow his masking tape whenever I need to 
Tell me I’m not alone in having a little weirdo!
