My soon to be XH has our 2 DDs every other weekend. The last time I picked them up they were quite dirty and eldest hadn't changed her clothes since Friday night (when I dropped off), collected them Sunday evening. When I pointed out that they didn't look acceptable he kicked off, said that I was nitpicking and that they used to get just as dirty when we all lived togeher. My sol says I should refuse to leave them with him if I think he's neglecting them, which I have done and it's not gone down well.
