Is it wrong to use sibling rivalry to get things accomplished?
I notice if I ask one of the girls to do something and they are reluctant, if I say “OK, your sister will do it,” suddenly they are fighting over the right to do the chore. 
Or else, at least the second one is happy to show up the first one by obeying.
haha… I do that too…Hope you’re feeling better!Don’t think I’ve talked to you since my birthday party… anyway, just wanted to say that I’m glad you came! And sorry Dave couldn’t make it!
I think it’s a great idea. When I was little, my mom used to challenge me to the Quiet Game. “I bet I can be quieter than you! Nope, I’m sure of it. No? Oh, prove me wrong!” For years (sadly), the trick worked. Then, even after I’d figured out her ulterior motive behind the Quiet Game, my sense of competition was so strong, that I still couldn’t resist trying to be quieter than my mom when she challenged me to the game. ~KTL
LOL! I try not to do this because I want to encourage a spirit of support and cooperation between them but every now and then giving in to temptation is ok!
Looking back, my mom used that all the time. Its not wrong! Its like saying, ‘who can clean their room first’ to get them to clean.
i do that too. it works wonders.
In our classroom I use a version of that. I ask a couple of the children (who are usually fighting over who gets to sit in a certain beanbag) who can be responsible today and act the most grown up. The one who acts grown up about it gets positive reinforcement, while the other one is left to feel guilty.
My short answer is that it all depends on context, situation and the specific end one has in mind.
leave it to jargon to say something helpful like “it depends.”lolAt least your answer didn’t contradict itself…
