I've been with my partner for over a year and he's got a daughter who's just turned nine. We live together and are now 9 weeks pregnant with our own baby. My partner is quite wealthy and spoils his daughter a lot because be only has her every other weekend. This has been fine because I stood back and just let him do what he wants as she's his child. But since we moved into a house together she doesn't respect either of us or our house or anything in it. She says horrible things and he doesn't do anything about it. When she's with us all she eats is chocolate and crisps, I ear really healthy and make kid friendly meals for every meal for her and she just sits on her phone and refuses to eat it. Her dad ends up just letting her eat her desert instead and it's really getting to me because our child will not be allowed to act like that and I don't think its fair that she'll be allowed to eat whatever she wants. Also the rubbish food is causing her stomach problems and she's had poo accidents while with us. Anytime I try to speak to my partner about it he says that I'm attacking his parenting and he's just trying to stop her from having a meltdown. He says he doesn't believe in discipline and he just tells her that she's upsetting him but she honestly doesn't care and just laughs in his face.
