To feel really uncomfortable?

[Deeperdown]

Taken friends dd away with mine just in the UK.
We are on a site with masses of entertainment and activities free.
We have paid for all her food so literally just spends.

They have sent £300. My dd knows they have sent £300.
I'm a single Mum, my Mum has paid for our holiday to give us a break as I'm on a low working wage.

Dds friends Mum knew all above as we told her. She's sent the dd with £300 dd has £30.

I feel like utter shit for dd. Every time her friend goes to the shop they can buy loads.

Take it, give her a small allowance for each day. Give the rest back to parents, tell them it wasn't needed. Perhaps use some for a day trip or entry into something you'll all benefit from. Take lots of photos of you all enjoying yourselves to share with her parents. You're providing their dd with a lovely experience, don't feel bad.

Maybe you could call her mum and ask if it was her birthday money? Something along the lines of 'it'd be such a shame for her to waste all her birthday money in arcades'... hopefully her mum will interject and give you a better idea what it was intended for.

Other than that, I'm not sure it'd be fair to just dip into it without asking like PP's have suggested - no take out/day out would be worth the possible fallout if her mum kicked up a fuss.

If you're worried about how your DD feels maybe have a quiet word at some point - make sure she realises that by not giving her money for arcades and crap that you can afford more treats for birthdays etc.
