Dd went on sleepover - Mother of friend had provided alcohol!

[Persephone70]

This is a WWYD.

Dd (13) went on a sleepover last night to a friends house - 4 girls in total, all aged 13 years and Mother of 1 girl at the sleepover house.
Daughter dropped off at 10.30am this morning by Mother of friend.
This afternoon I get shown a snapchat screenshot by a child in our street, depicting my Dd with a bottle of blue WKD in her hand and it says 'my friend drinking alcohol for the first time' - it had been posted by the friend who had hosted the sleepover.
So, I go banzai at my Dd and ask what on earth went on at the sleepover! Dd breaks down and says Mother hosting sleepover had bought WKD for the girls, thinking it would be fun!? Dd vehement that she kept refusing the offer of trying it, when offered by friend, but friend was getting angry and cross so dd tasted it (friend took photo of this). Dd said to friend that she didn't like it, as did other 2 girls at sleepover - so friend hosting drank the WKD herself and fell asleep.
AIBU to be absolutely fuming at parent of hosting child for buying minors alcohol and thinking it ok to give my child alcohol - without even asking me?!
What should I do? I have no contact number for the Mother, but do know where she lives (obviously).
Sorry if it ses a bit disjointed, but didn't want to drip feed.

When my dad was 9 she went to a sleepover and they put the exorcist on. She had nightmares for weeks. Was terrified to go to bed. Some people are ridiculous.

I am going to set up the 'get me out' text with dd. I had read aboit it before, but hadn't thought to do it myself. I said to her she should have sent me a text, but she was worried what the others would think. I have also said that in future she just gets hold of me and lets me worry about making up the get out reason.

I'm a pretty liberal parent, but giving alcohol to someone's else's 13 year old without parents consent is not ok!

I don't think I'd say anything though, your DD sounds sensible, it's a good opener for a conversation about how to cope with being put in an awkward situation where you're facing pressure from peers.

So you went Banzai and read the riot act?

I mean you are right to be very vexed at alcohol being made available but am not sure fire first, ask questions later is really the best approach. Still, as long as you are feeling better, that's all that's matters really......

Thanks for the advice, scottishdiem - very helpful.

Scottishdiem I actually think it was the right thing to do. I certainly did the same and my dd said afterwards it was seeing me 'loss my cool' that made her really realise how bad the situation was. Sometimes being calm isn't possible or even right as it seems no big deal.
