Daughter is 8, had the same best friend for years. I know and get on with her parents. My daughter has a 5 year old sister, they get on really well and play/draw/watch TV and generally spend most of their time together.
Daughter's best friend is an only child and gets very lonely in the holidays which I sympathise with. However I feel like they sort of commandeer my daughter at holidays, so far this holiday she has spent Saturday afternoon, went on dinnertime Monday night, slept over and spent all of Tuesday daytime there, came home Tuesday evening and I've just had a text asking if she can sleep tonight and go ice skating tomorrow - the venue is a good few hours away so will be another whole day.
My daughter does love spending time with her friends and I wouldn't want to discourage it but I also want time with my daughter! The mum openly says that it makes her life easier with her daughter being an only but she's effectively making my younger an only 🤣 it's a very first world problem but I don't know if I just need to start saying no? Or is that unfair on my daughter/friend?
I work term time only so holidays are my only real quality time with my kids.
