My two step-gds and their mum are coming to visit next week. I know they are a bit wild - they get over-excited and charge around screaming and I've said I don't want them to go into the sitting room where I have some (to me) precious and breakable stuff. This is my house, not shared ownership. My partner (their grandfather) is cross that I am disparaging his gds' behaviour. And they are awful at meals - toys to distract them at the table, take forever to eat anything, ask for food other than what has been prepared for them. I am tempted to come in heavy and say 'my house, my rules' - no toys at the table and if you don't want this perfectly appropriate home made food, fine, but no I'm not making you anything else,' but I know it will lead to bad feeling. To be honest, I am dreading their visit.
