OK, so SIL has put a post on FB. She's apparently let her 6 year old play out in the front, on her own, on the basis that she stayed where her mother can see her.
Front garden has no fence, no gate and not much to play with. Also currently has a huge skip in it.
AIBU in thinking, seeing as she's there alone, and SIL would also have been taking care of a nine month old baby, that this level of independence isn't really age appropriate? She's argued with DN plays out the front at SIL's mother's all the time, although this is with SIL's younger brother?
I know someone will tell me to get my judgey pants out of my arse crack, and they are grating... but this is my niece...
