I'm fully prepared to be told that AIBU, just want to gauge how others would have taken this.
DS14 and DD13 went down to see the in-laws for 4 days over the bank holiday period. About 4hrs on the train, plus cycling on our side and car ride on their side, so a considerable distance. 5yr old cousin who lives much closer to the in-laws was also visiting. They love seeing their cousin and playing with her, but from past experience can be pretty full on like toddlers are, excited to see their only cousins etc. After a couple of days of relentless playing (7am-10pm) DS and DD phones me, DD saying she is missing me, she gets emotional when tired, and DS saying he is not allowed a break from the playing. MIL overhears this and snaps at DS, bans him from dinner, further telling off etc etc, and ultimately they were sent home the next day as they had had enough of his moody, petulant, stone faced demeanour and refusal to apologise for saying telling us he needed a break. They were meant to come back the day after, instead they were taken to the station and dropped off, they came home at 9pm last night. Is this reasonable? I am totally on board with telling off for bad behaviour and feel that it's up to the grandparents to do that if necessary, DS can be like this sometimes, but in this instance, couldn't they have suck it up for a few more hours and sent them home the next day as planned? This is the first time ever that they have gone down without us, and according to the in-laws won't be happening again. Feeling sad for the kids mainly.
It's not the chastising I don't approve of, it's the way they were sent away abruptly.
