I had my brother (8) and sister(10) to stay tonight and when I picked them up frankly they both stunk. The first thing I did when we got home was get them both to have a bath. At tea I asked them when was the last time they'd had a bath/shower and they said last Friday. They said that mum says she doesn't care anymore (they did resist my request to have a bath, my brother only agreed when I threatened to scrub him myself). Should I have a word about this or would I come across as lecturing her as I've got a 5mo ds.
