I just deleted a whole long post on parenting because I'm not gonna stir the pot and throw this thread
Here's a story:
A friend of my BF has kids. They're considered brats because they do what they want when they want, but I think they're good kids because Mom is "one of those" who chose to just pump them out and let them wander the neighborhood as soon as they could reach the door knob. She had no clue where they were all day - dinner time she would scream out the door to them for them to come home. Sometimes she would call my friend asking if my friend had seen them that day.....Anyway, that woman used to tell her kids stories of how wonderful Disney is and she can't wait to go. The kids had no clue they were not included in the trip. They spoke for months about how they can't wait to go to Disney.
Well, That woman and her husband went to Disney and left their three kids, all under ten, home with one of their grandparents. That woman is known throughout the school and town for this now. Everyone thinks she's a schmuck.
I agree with both sides of the issue. I agree with sticking to your guns. I am strict with my kids and now that they're teens they help me out at all the right times (after holiday parties, at others' homes, etc.) and I don't even need to ask. Of course, they still won't sweep until I ask, the dishes pile up, the bedrooms are messy

Typical....That Is Typical. In-Fighting? Always!

That's normal Sibling Behaviour. "They" say that sibling rivalry helps them in the long run as adults at work and in relationships. They learn how to "fight" or "get along" with friends and co-workers. It makes them stronger. I can definitely say that my relationship with one of my sisters, who is bi-polar, has helped with my relationships as an adult.
So no matter what, kids are gonna 1. Not Do Chores until screamed at; 2. Whine while doing said chores; 3. Fight with each other, incessantly
For the other side, read the above story. Kids are kids. "You have three minutes to get your butt out here to sweep this floor or you can forget about using the computer tonight" and follow through. "It's dinner time.. We're gonna eat....If I have to ask you to clean the table off and do the dishes, Once Again, without you running off outside to play, then I'm taking away your cell phone for the day".
This has worked for us.
Also, sometimes one parent gets a little crazy. Sometimes I have to pull my husband aside and tell him to knock it off, they're kids, you had a bad day, stop taking it out on us (not abusive! Normal stuff!) or he'll say that to me. My grandfather would do the normal parenting stuff, yell for no reason, etc. But he always Apologised if he was wrong. I've learned to do that with my kids, and I taught my husband to do the same. It's best to discipline, but life is tricky and everyone deserves A Little Slack......
I say stick to your guns, but I cannot say that I agree with cancelling a trip to Disney. You know that saying, Pick Your Battles? Cancelling a trip to Disney for young kids is like the end of the world. Think about the above story. That woman is known, and forever will be known, as The Bad Mom Who Didn't Take Her Kids To Disney.
