My in laws and I normally have a good relationship. They help us with childcare on occasion and enjoy taking dc out on weekends. I sometimes worry they do you much as fil hasn't been well and I don't want to tire him out. This week they are helping out a lot as dh has unexpected long days and it's busy week for me at work. However they have been returning dc very late for a school night even when asked not too and dc aren't getting the rest they need. I am very grateful for the support they give us but I do need them to understand that dc need to be home on a school night for shower, homework etc as well as the fact I would like to spend time with them. Dc also come home testing the barriers with me as they let them get away with murder. Any ideas?
