Christmas Lights

Mostly from the tree, but the red ones are from my kitchen window... the neighbours must have thought I was mad.

Anyone got any hints for for stopping a 1 year old from attacking the christmas tree? I did think it was him who would be my problem, however after coming downstairs this morning, the 'lovely' Isobel had stripped the tree of all decorations apparently because she was counting them! Hmmmmm!
