My Sil asked if if her DD 14 can stay with us for 3 days this week so sil can attend the funeral of her uncle. We said ok but she has allowed her DD to become vegan and wants to bring over vegan foods for her to eat while shes here. I told her NO I said that in THIS HOUSE we eat what is served and we do NOT allow a child to tell us what kind of diet she is going to follow. I said she may let her do that BS in her home but intill they turn 18 DH and I will make any descisions regarding our kids diets they are 12 and 15 She is pissed and said well fuck it I'll find someone else. Her DD is staying with a neigbor for those days now MIL and Fil are pisses saying we should have just let it gol Umm NO this is OUR house and OUR rules if you dont like it dont let the door hit you in the ass on the way out. Dh agrees. so I dont really give a fuck what they think.
