My daughter is 4, will be 5 in October and starting school this year. She still wears nappies to bed. We are talk about and have a few books about topics such as underpants rules and privates, all very age appropriate of course. She knows she has 5 people who can help her with things such as toilet, changing, nappies, bath/shower etc. These are myself, her dad, my sister, my mum and her dad's mum. She stayed over at my sisters about a week ago and she mentioned last night that my daughters partner put her nappy on. They both know about my boundaries on this and how I feel about it. So I casually messaged them yesterday and he has come back saying he is extremely offended and calling me sexist. I don't feel it is his place to call me sexist, I don't agree with things about his parenting but it's not my place to say this to him. And it's also not like it's new information, he knows how I feel about it and has always been understandable and respectful of it. Am I being unreasonable with feeling annoyed at his response and feeling it was uncalled for.
