My parents won’t let me parent and I feel trapped

Am I in the wrong or not? I feel really emotionally exhausted. My mum and dad will always team up against me so they get what they want.

1. My son is on the bigger side and I’m working on getting him healthier and giving him treats in moderation. The other day my parents bought him a large brownie slice and he ate it. We then went to another place and they offered him an ice cream and I went “guys, can we not agree his large brownie slice was his treat for today and we’ll make healthier choices with his snack now?” They went “dont be nasty he wants one so we’ll get him one” and I went “actualy no, I don’t want him to have one” so they both started arguing with me. This is just one example of a daily occurrence.

2. My parents are inappropriate for his age the way they speak to him. He is almost 7 and they say things like “baba boy do you want some choccy” and I went “hey, he’s coming up 7 how about we speak to him in an age appropriate way and say chocolate” they both ended up losing it with me saying “you either want us to talk to him like that or not at all” which felt really controlling like it’s all or nothing.

3. My parents will not allow him independence for example I tell him to go into his own cubicle in the toilet and my mum followed him in. I went “he is almost 7, things he can do independently we need to promote” they then both told me I’m a disgrace and I will end up lonely and with nobody to like me.

4. They give him no personal space. I tried to get pictures of him opening his birthday presents but my mum is constantly kissing him. He will be playing and minding his own business and they will say “kiss me” constantly and I said “please, refrain from demanding things like that. Allow him to know he has a choice” they do a fake cry if he chooses not to and tell me I’m a nasty bitch when I tell my son if he doesn’t want to kiss someone then he is still loved and respected when he says no.

5. They argued with me when he was a baby because I carried him out of his Moses basket and they told me I should never ever do that while he is asleep.

6. They will not respect my boundaries and BOTH argue with me when I tell them to stop doing something. They will tell me I’m nasty, they’re both in it together so will both shout at me and tell me if I keep going I will end up hated. I feel really trapped that it came to a situation of “let us do what WE want or you will be lonely”.

7. I moved out (I’m 24) and they told me I’ve flung my family away but my uncle goes missing for months on end he comes back and they give him money and run around after him but I see them everyday and I’ve flung my family away because they don’t have their own way.
