My Step daughter changes her sons pooey nappy and does not wash her hands afterward. Her partner also does not. I did not like this in my home,but didn't feel I could say anything to her face as I did before with her 1st child as she did the same,and i got a mouthfall from her. This time round, I texed her when shd gone and she has not bothered to text back. How would anyone else handle this situation? It is my home after all, my family are hygenic, saying this my partner would side with her as it's his daughter
