How to stop the neighbor kid from coming over?

My daughter is Seven and the neighbor kid(4 houses down) is 10&1/2. The girl is an only child and gets catty and negative when she doesn't get her way. She is more interested in playing Minecraft on my son's Xbox than playing with my daughter so we took it out if the equation and she is not allowed to play Xbox at our house now. My daughter is really into dance and tumbling and takes classes year round, her friend has started badmouthing that now and I'm afraid she will sour that, like she did Loom bracelets and dolls! Her mom and moms boyfriend seem to enjoy having a free babysitter. They send to our house after school and want to leave her til7p.m. I don't want to piss off the neighbors but summer is coming and my kids enjoy having their friends over and I don't want her spoiling it. My husband feels sorry for her since she says she has no friends, but I'm starting to see why she doesn't. How do we end this non-friendship w\o a neighborhood meltdown?

It sounds like both the kid and the parents need a good smack on the rear end.
I'd tell the little brat point blank how it's going to be. And I'd stand up to the parents, you pay me for watching YOUR child all this time, or you STEP UP and be her parents.
No one likes being to things like that so it will probably get the brat off your hands while the parents fester over you telling them how it is.

You say no. When she is allowed over, you set rules of no mocking other people's interests and enforce them - if she doesn't comply, she goes home. Period. You tell the parents she's not allowed after school, and that any visits during the summer need to be approved at least a day before because you have lots of family plans.

Quite a delicate matter i see

well her parents i do not like straight off the bat but it is understandable. I probably should not try to help here as people who take liberties as such infuriate me and last about ten seconds.

obviously there are many ways to deal with this matter but which is best. Do you send her home when she comes calling more frequently and by that i mean stand at the door and say no she is not playing today you will have to go home sort of thing.

or perhaps you and your partner go talk to her parents directly and address the issue in a polite and civil manner. After all why should you have to look after someone else's kid to such extremes when you have your own to be taking care of. Is it that they are concerned for there daughters isolation or is it just because they want to lump you with her so they can have free time to engage in the benefits of a new relationship or laze about or whatever they do. It sounds like you are being taken advantage of.

sod upsetting the neighbours let them sulk all they want put them in there place with a very detailed and rational and honest explanation that they can't argue. And if they do not want to even accept or listen to as why you have made this decision then they are not even worth the time of day. I like your husband though it is nice he cares enough to want to help there kid

just tell them you want her to play with children of her own age as she has outgrown already the things your daughter is interested in and there daughter being bored of those things is spoiling that part of childhood for your own daughter. So that is why i would like to keep them separated more often. So stop sending her over all of the time. Once a week is fine perhaps

Burn their house down. They'll leave the neighborhood and take the kid with them.

Consider a mote.
