I live in a 1st floor maisonette so my garden has a gate that leads on to a path & small grassy area outside my front door. There is a larger grass area along the front of the houses. My children, 8 & 5 play in my garden & in the area directly outside my front door, often with the little girl, 6,from next door. A family of children, all cousins ranging from 4 to 11, who live much further up the road where the houses have front gardens rather thanthe open grass area often play & ride there bikes on the grass area near my flat & became friends with my children which is nice & I have been fine with them playing in my garden too but now feel I am being used as a free child minding service. 1 girl who is 8 is continuously playing dangerously, climbing on my garden furniture, shed etc& I have had to speak to her mum & 1 boy is 7 & has ADHD & autism & does incredibly dangerous things such as go through a neighbours ashtray to find matches etc. He has broke numerous items in my garden & his mums response is always that he has SN & needs watching. That is fair enough but surely I am not expected to watch him from 4 til gone 7 every evening??? I am currently pregnant & suffering with awful nausea & tiredness, I do not need to be supervising every child on the street when mine are well behaved & playing nicely. These childrens parents & nan are childminders so are looking after other peoples children for money while leaving theirs to me. AIBU to think this is a bit of a piss take?
