to expect sister in law to have brought extra kids bedding for Xmas visit?

[camperkid]

Brother, wife + 2DS have come to stay for 4 days. Anyway, woken at 4am this morning to find SIL lookin for clean sheets as 2DS (7+10) had both wet their beds. (reminder - no pepsi tonight). So washing machine now on second load before 6.30. Anyway, appears this is now nightly (good job I had covered the mattresses eh?) She has said can she have extra sheets tonight? FFS - there are 5 extra in the house anyway. How much bedding does she think I have?

i was going to say you are being ur to the op from the title, but having read the op, i think the sil should have brought the extra bedding if she knows her boys are likely to d o this.
ds in only six and a half, and we either never ever stay the night somewhere, or always take pyjama pants with us, which we use daily at home aas well.
