Oh, definitely make him wait, especially if it's something he can easily get himself.

Make him wait, he's a punk and needs to learn manners.

From personal experience, kids (sample size 1) are a nightmare at that age range. Mouthy, demanding, and entitled and complaining about everything that isn't just the way they want it. Every small infraction against their demands makes it "the worst day of my life." But you have to weather through it and make sure they learn they have responsibilities if they want to have privileges, that they need to wait and work for what they want, and that disrespecting legitimate authority generally brings negative consequences, otherwise they won't become well adjusted adults.

Definitely make him wait. Has he just started being like this? Getting to that teenage stage. He probably get worse if you just give him what he wants, when he wants it. You's got this!

Have you considered tell him to shut the hell up?

stop this nonsense, if your child wants something make them earn it, understand somethings might be bad for them (sweets and garbage) I set a rule for all the kids to follow where if you act out you work out, but also if they'd like said thing that is bad for them, I put an additional workout on top of the disciplinary ones as well, they understand life ain't fair and you have to work for what you want, it teaches them that being a jerk just makes them have to work more just right off the bat just for the things they want, I try to keep a constant reminder that their attitude and reactions to life can plummet them in the real world but at the same time if controlled and properly taken care of will help them sky rocket. it is not your job to tell them how to feel it is to help them learn to process things on their own. you have all the short cuts and cheat codes to this world, don't forget to teach them to your loved ones, give them the tools they need to fight for what they believe in

Option 3. He doesn’t get what he is asking for if he is rude.

Time to beat is ass...he’s old enough to know what respect means

You can't decide whether you should actually act like a parent and teach your kid respect?? I guess it's completely obvious why your kids acts the way he does. Bad parenting.

Don't make him wait when he's being rude, just don't give it to him unless it's something he essentially NEEDS to survive. Then make him wait since a few extra minutes won't kill him.
