So yesterday my DH and our two DD went around to my MILs (SIL lives there has no children.) When we arrived everything was good, they had just finished eating dinner and had made a cuppa, so I went into the kitchen to make one for me and DH. Everything was fine until my eldest daughter (aged 2) dropped a date on the carpet to which she was told by her dad to pick it up and to be careful. SIL snaps "she's going to make a mess" gets up and walks into the other room.
For context - I am very aware of the mess young kids can make so I ALWAYS clean u after them and correct their behaviour when at our own home and more so at somebody else's.
Anyway she came back in and had an obvious cob on. She went into the kitchen to wash the dishes and my eldest followed her. When they came back in she had got DD a little glass of water. DD was trying to climb on the pouffe to sit to drink her water all while SIL was holding the water. As she's climbing up SIL says "do you want your water DD says yes and is still climbing on the pouffe SIL asks her again within seconds DD doesn't reply as she's still trying to climb on the pouffe. SIL swings open the kitchen door and puts the water on the counter. DD gets on the pouffe and asks where the water is, SIL ignores her. DD asks again and was ignored. She asks about 3rd time to which SIL says "did you want it you didn't answer me" then storms back into the kitchen to get the water and gives her it. DD drinks the water and then tries to give her it to put high up so that her younger sister can't reach it. SIL says just put it next to the TV so you can reach it bla bla bla.
Just to add - i didn't interject at any point because I wanted to see how the situation panned out and to see how SIL behaves with my kids when she thinks nobody is listening/watching.
DH was speaking to his mum so didn't hear any of this.
Anyway I was obviously fuming, I've woke up this morning fuming even more. So my question is going forward what do I do? In all honesty I don't want to go to someone's house who treat my kids as an inconvenience and IMO are just rude to them, on the other hand I want a similar situation to happen so I am in a position to interject so SIL knows I know how she can be with my kids.
WWUD in this situation?
AIBU - Yes your a touchy mum
YANBU - I'd be fuming too
