We just had a parcel delivered - a large box full of small bathroom fittings and electrical bits - all packed in millions of little polystyrene "s"s. DD (17 months) is now swimming happily in the box (minus all the stuff we bought obviously!). I can't believe how much fun she is having! I think when she gets bored I'll have to put the box & polystyrene bits away on top of a wardrobe, and keep it for those grumpy late afternoons...
And its got me thinking - what else might I have around the house that she would enjoy more than some expensive ToysRUs creation?
