I'm back!
I am sorry, I posted this, forgot about it put it to the back of my mind and was busy with family stuff. I haven't checked my emails all day, and I had no idea this would be so popular.
Hello
I will answer some questions - although I would have preferred to keep these details out as I don't particularly want to be recognised.
DD, who is 9, went for 5 nights to Ireland to stay with MIL's husband's relatives. And while I am extremely grateful no matter how much the holiday cost, it wasn't the long and expensive package Holiday somewhere hot that some of you are imagining, just in case that's relevant. MIL did generously pay for flights, which I think were about £50 plus whatever she paid for baggage, plus take her on a day out, but it was mostly spent playing in the family home which is a large country estate, playing with the step-FIL's family kids, and riding their horses. She didn't buy any of the food either, although I believe she offered. A wonderful, memory filled Holiday, but not hugely expensive, if that's relevant.
It also isn't a hot country, with the weather being more or less the same as here, which hasn't been great (its nicer now she's back - sod's law), so I put the sun cream, which was unopened, in as a precaution, and I wouldn't have expected it to come back all used, and even if it had, my DD would have at least got use out of it and no-one's money would have been wasted.
I also would not have expected all of the hair products to be used after only 5 nights. You only use a very small amount daily and they usually last a month. I had had them three or four days before I packed them.
It was not shampoo or conditioner, they were styling products. Not essential but they do make her hair tamer, neater and manageable. I use cheap, tesco own brand shampoos, you'll all be pleased to hear. I wanted her to look nice on Holiday. I didn't pack any shampoo but MIL did bathe her and use a shampoo and conditioner, I have no idea what brand. She didn't use any styling products and as a result, her hair looks crazy in all the photos and was very wild and tangled when she arrived home, but no big deal as long as she had fun. Her toothpaste, by the way, was under 100ml so wasn't chucked.
Yes, I was clearly verbally told the luggage was going to be checked in. I was even given a copy of the paperwork and could clearly see that hold luggage for each passenger (MIL, her husband, her friend, and DD) had been booked and paid for. I therefore had no reason to suspect luggage wouldn't be checked in.
It was not checked in because DD had a beautiful new Laura Ashely suitcase, bought by my mum (again, very generous) that she was very attached to and didn't want to hand over and MIL decided to indulge her and let her keep it with her. No-one thought of the hair products until they were being chucked in a bin.
I didn't think the case would not be checked in because a) I had clearly been informed otherwise and b) I actually didn't think it and small enough and I'm still surprised it was and I didn't think you were allowed more than one bag? She carried both the backpack and suitcase into the cabin with her.
I didn't give a hair care handover but DH, who drove them to the airport, was responsible for giving a handover as the last parent to be with her and the one to be actually handing her over and obviously as her dad, he is just as aware of her hair routine as I am.
What else was there? Oh yes, I shouldn't buy my DD expensive hair care products if I'm so poor (I'm paraphrasing). Well, I spend £20 on her looking nice and presentable (mainly with school in mind) every month in my big monthly shop. It's budgeted into my shopping and it's perfectly manageable. I have also tried many products (including the lidl brands suggested) and I know what works well for us.
However, if I have to buy these twice because they've been thrown away, then that's £40 I have to budget for instead of £20, and that's a little less manageable and means less other things. It doesn't mean I cant afford £20 on hair products and it certainly doesn't mean they don't get lunch, so please can people stop saying that, for goodness sake.
It means that once I've done my monthly shop, and paid my bills, I have a specific amount left for other things, and during the school Holidays when there is more to pay for, this amount is very specific, so I don't want to have to spend some of it on replacing something I've already bought.
I am grateful to the people that understood this and didn't make rude comments or give patronising "advice".
As I said in my OP, I'm not going to ask the MIL to pay. I was merely curious as to whether other people agreed that I felt she should have. Thank you to the people that joined in but the patronising and rude comments have sadly made me wish I hadn't bothered.
I'm sure people will nitpick at this reply and that I will be back XD
