Please help, My ex looks after my two girls (12 and 10) most weekends. The eldest likes to do park runs on Saturdays but my youngest isn't really bothered. I found out recently that my ex and my eldest had done a park run in a large Scottish city (they've never been there before so an unfamiliar location), and my youngest had been left alone in a play park while they did a 5k park run. Looking at the course, the majority of it is outside the visibility of the park so there would be no way of checking whether she was safe in the park, except a few sections. A 5k takes around 30 minutes to complete - it does circulate the play park but on a very wide basis. Am I being unreasonable to think this isn't okay??
