Just like men waiting for luggage at the carousel at an airport guarding their space so they will get their bag off first, I have noticed a whole new breed of competitive swinging mummies.
On a good day at the park two swings will be available side by side. On a bad day we have to wait our turn. There are generally two types of mummy at the swings. There are those, like me, who as soon as a queue builds up feel the need to encourage the children off the swings. Then there are those who have waited their turn and are going to make sure their child has a long turn. I have even witnessed mummies who use a swing like a highchair and spend 15 minutes spooning apple sauce into their baby with no swinging being done at all.
On Hampstead Heath one day we found two swings, one available and the other occupied by an overgrown toddler, too big for the swing, with his Grandpa. Grandpa was negotiating some sort of deal on his mobile phone but every so often came back to give another push. After 10 minutes of switching A&E over, the Grandpa finally finished his call and persuaded his bored grandson out of the swing offering us the seat as if he had just noticed us and was doing me a huge favour.
There really should be some sort of swinging etiquette. 2-3 minutes satisfies even the most excited swinger. Just because 10-15 minutes pushing a child is easier for the adult, it's time we learned to be more adventurous with our toddlers in the park.
