Over the years I have had four children, so I have been to a lot of playgrounds. I could write a book on the best and worst playgrounds in south east London. What I have noticed compared to when I had my first child about 13 years ago is that these days, I am often the only mother in the playground. When I had my eldest, there were lots of mums, dads and childminders with their little charges clambering up steps and zooming down slides, but now I am usually on my own. It’s just me and the little lad.
