To be annoyed with this other mum?

[IrrelevantPeasant]

It’s parents night next week at DD’s school. I suggested to her friend’s Mum that while she is in for her appointment with the teacher I would look after her kids and she could look after mine during my appointment. The school prefer it if you don’t take kids along with you. Friend’s Mum agreed to this. Tonight I asked her if her DDs wanted to stay for dinner that night too but now she tells me that she’s made the same arrangement with another friend and I don’t have to look after her kids any more! She says that she’ll still take my DD so I can go to to parents night alone. I’ve told her it’s OK and I’ll just make other arrangements. AIBU to feel a bit put out by this?

Sounds you're cutting off your nose to spite your face, tbh.

Sounds ideal to me, you still don't have to take your child but you don't need to babysit hers either. What's to get annoyed about?!

Sorry - why are you cross? She hasn't let you down, has she?

Hadn’t thought of it like that auntLydia! I guess I feel like she had made an arrangement with me but has had a better offer elsewhere so chosen to go with other friend. I should add that when my DD goes to her, her own DD will be with the other friends Mum

Maybe her dc know the other woman better.

your offer looks for the appointment time only, probably the other mum takes her DD ( and maybe another sibling? ) for the whole evening?

Maybe her DC know the other lady better than you and so she feels her DC would be happier with her. She is still offering to have your DC as promised so I think I would have thanked her and agreed. Although now you have to find alternative arrangements... and are you able to do so?

So you were going to look after her kids and she would look after yours.

Now she is going to look after yours but you don't have to do anything in return.

So she has offered you a better deal and you have turned her down in a huff

I await her mumsnet thread 'what have I done to offend IrrelevantPeasant I thought I was doing her a favour but she's gone all prickly on me'

Score! She looks after your DC and you don't even have to look after hers! Call her back and accept.

Aww that's kind of her.. clearly there are a few Mums in the same predicament come Parents Night.. grab it with both hands Lady...

Of course YABU.
Why would you not accept this ??

She's clearly able to help out 2 people rather than one. On this occasion that means you don't need to have hers back. Who knows, there might be the chance on another parents evening - there's lots of them to come you know.

Kurri and Tawdry, DD’s friend would be with her mother’s friend. OP’s DD would probably not feel comfortable being alone with friends mother. I know my DD wouldn’t have wanted to do this.
I’d feel a bit deflated OP, especially since you proposed the idea first.
