Sounds perfectly wonderful! Wet bums on the way home is perfect!
I once took my kids to go to see my Mum and we took her dogs for a walk in the New Forest with my sister and her children. The kids managed to find a huge puddle and asked if they could paddle - obviously I said yes! It was only when they started to fall over did we realise how deep it was and I didn't have spare clothes for any of them! Luckily my little brother drove up to play with us and he had a boot full of slightly smelly, but dry rugby shirts! So my kids did the 2 1/2 hour journey (and had to stop on the way home for a wee) in smelly far too big for them rugby shirts! It was hilarious! Ben didn't think so and Hazel didn't like the smell, but we convinced her it was high fashion and amazing and Fern was just happy to sleep on the way home! Good times!
