I would say relax.
My DGC are much better behaved here but I've seen tantrums and naughtiness in their own homes.
But, do you know, even I'm better behaved at other people's houses and I'm 54. If I want to have a strop in my own home, I'll bloody well have one!
And so should my DGC!! Safe to do so, you see.
