Keeping up with the Grandparents

Letting your child spend too long with their grandparents can have its downsides I have discovered. I have just been told by no.1 son that he expects £2 rather than the customary £1 next time a tooth comes out, as this is what he received from the tooth-fairy at Mamgu (Welsh for Granny) and Granfer's house. He has also just asked me to put his pyjamas to warm on the towel rail so they are ready for when he gets out of the bath! This indulgence has also been instigated by my mum. How come I didn't get that kind of treatment from them when I was a child?!
