Riley loves puddles :) paddling in puddles is a great way to get out and about on a wet day! All you need is a good pair of wellies (Riley has my old pair from when I was little) and a paddle suit (Riley's was £3.50 at an NCT sale).
Then just find a good puddles and jump! I think we are very lucky, Riley is a very hardy little person, she just loves the outdoors and so doesn't mind being out in the wind and rain. Makes the winter months much easier to cope with as you can get out and about just making sure we take lots of warm dry clothes and waterproofs with us :)
