I have been trying to figure out solutions to my children's constant bickering. It really seems to stem from a place of not being heard or feeling like they are lacking attention. So I thought if we had a time for stretching each day where we could all take turns listening and being listened to that might help.
We all take turns going first second and last so no one feels like they are always last and someone else is always first. When we attend music lessons, art lessons, etc. we also take turns going first and second now. I have to say it seems to be helping, each child having their own time to be heard and paid attention to seems to be a very simple yet very important thing. Who know! Sometimes the smallest adjustments give you the biggest rewards.
