With all the wet weather we have had, we were getting bored not getting to the park, so we decided to bring the park to us. Well not really an entire park but the swing. I saw this on pinterest and thought it was a great idea.
All that was needed was a chin-up/pushup bar, about £5 , and a swing, about £7, both available from many shops including amazon and eBay
Took only seconds to put up and April loved it. Even better that it is a physical thing to do than sitting watching tv .
