Dh and I are having niece and nephew for 3 weekends this month, on a saturday for a sleepover, mid day till mid day on Sunday. From experience SIL has always sent them with instructions for us to assist with homework/reading etc, it used to be just nephew but now neice is at school too as is my ds.
I would love to be able to say 'sorry, i'll look after them by all means but don't bring homework here'
I would not expect someone who was doing me such a favour to also do ds's homework.
Am I being unreasonable?
