My dd is 7 and her best friend is often at our house which i don't mind as she's a lovely kid and they play really nicely together and she actually keeps my daughter amused which obviously makes my life easier the problem is her mum, she never picks her up when she says she is going to, sometimes she's over an hour late. I don't want to stop her coming round but I don't know what else to do as it kind of screws up our evening routine or any plans we have. Iv said stuff to her about it and I will msg her and ring her when she's really late but there is always an excuse. My dd also goes round to her house and I always fetch her when I say I'm going to would I be unreasonable to start doing the same to her.
Yanbu: be really late a few times see how she likes it
Yabu: That's really petty and unfair on your daughter
