How to get partner on side?

[Anjied]

Hi all
Looking for some advice here please
Everything I do or try to do with our 2yr old daughter my partner / her dad does the opposite for example she wants chocolate at 7am I say no so he goes & gives her an adult size bar. I try to encourage her to drink water & he gives her very sugary drinks.
When I try to explain to him she shouldn’t be having that much sugar he says I am being mean & she’s a kid
It’s not just around food either it’s her behaviour too I am encouraging manners & he just winds her up so she shouts & screams
I don’t know what to do as every time I say something he turns it on me
I am not saying he can’t have a say in her upbringing we just need to find a middle ground but he won’t it’s all his way but when she is then bad cos she’s had too much sugar & she is screaming he moans at me about it
Anyone else had this with their partner?
Advice on How to approach & change things would be good
Thanks

Are you still with the partner? Parenting book?

To be honest OP, from the sounds of it he's either an absolute thick-as-shit moron, or he has zero respect for you and is deliberately trying to fuck with you.

Whichever it is, you need to think carefully about whether or not you want to stay with him.
