This is great!!!

Jumping on beds - fully endorsed in this house if you don't jump on the bed, there must be something wrong with you (or you're too tall & hit the ceiling fan).

Blowing in the milk - why not??

Water fights - as long as you help in the towel dragging of Matilda around the house afterwards... (after a water fight we put Matilda on a towel & drag her around to mop up any water spilt)

Days off School - hmmm.... we'll see when the time comes what Matilda is like, but I'm sure we'll let her chuck a sickie now & then

Clotheslines - hmmmm I think DH has already started this with her.

Running in the house - well... she doesn't walk.
