I think my oldest two need some sort of team work exercises or something. They can't do anything without bickering about it. Dd2 especially likes to screech about everything and dd1 is so bossy, bossy doesn't even begin to describe it. Here the last few days it's started as soon as they get up in the morning. I can't take it anymore, especially not at 6am.
A little bit ago, we had to stop their assignment early because they were fighting over a glue stick. I made them stop, put everything away, then mediate while the gayatri mantra played in the background. No particular reason, except that seemed much more peaceful than bickering. I have relaxing music playing now, and sent them off to do other things.
