Don't you hate it when you ask your children to do something, and they ignore you? You think, "what? are they deaf-- disobedient-- why won't they listen and obey me?"
The problem: They're kids. They hear your voice so much, that sometimes they tune you out, especially if they hear you ask them to do something they don't want to do.
The solution: Sing. Sing your instructions, then whisper your instructions. Now you've caught your children's attention and hopefully they'll quickly follow through with what you've asked them to do.
This can work for toddlers learning to put away toys (Barney's clean up song www.youtube.com/watch?v=Dz-3Kxx3EQY) or teens who need to clean their bedrooms or wash the dishes, etc. Try singing in an opera voice, or country style, or with a proper English accent.
As parents, we need to "lighten up" and have fun. Singing makes for family fun.
