To not want my 14 year old stay home alone till all hours of the morning

[Cadburyssurpriseegg]

ds went to his cousins house (14 and 7). They and sis in law asked about a hundered times if ds can stay over. I said ok . I then find out around 12 am that sis in law and her husband have buggared off somewhere and left them home alone. Till now they’re not home. She’s not answering my messages and she doesn’t pick up either.
aibu to be pissed off about this ? I mean 14 is still too young to be left alone at this time isn’t it ?

It doesn't really matter what age we or our children were comfortable babysitting overnight, the fact is the OP is not comfortable with it and it should have been discussed with her first. It sounds like the SIL wanted extra company for her 14 year old while she went out partying leaving them to babysit.

Totally unacceptable - asking someone to come over to babysit, and paying them, is one thing. Inviting them over to stay the night without telling the parents that there will be no adults present is another thing entirely. At 14, the child's parents still need to know the actual circumstances before they consent to putting their child in that situation. I would be absolutely furious at such duplicity.

Up watching tv at that time and watching god knows what highlights the fact these 14 year olds still need parenting. I wouldn't allow my 14 year old to stay up that late and unsupervised. I don't expect many parents would.

If there had of been an issue it doesn't sound like your sister was contactable. She took responsibility for your child and let you down. Never again.

Yes. They used my son as a babysitter. Ds is a responsibile boy and they know this. While their sons run wild at home.
They finally arrived home at around 4 am. I’m absolutely fuming still and so is dh. He’s going to have a word with her today. It’s the last time he will be going to them.

I would be fuming that they clearly had used my child as a babysitter

surely the 7 yo's older brother is the one babysitting?
