Raising twins means you get used to seeing double – double buggies, double changing mats, double potties, even double favourite toys, but the double spacehopper has to be the most fun twin invention ever. It’s from the Science Museum and was a present from our friend Nichola.

Of course it’s also double the fun, causing double the giggles and in order to make it hop, it’s led to double efforts of co-operation.
