I designate a task for her. She controls the speed of my cake mixer. Easy and fool proof. Since she's so eager to help me out and can't wait to get her hands busy, I make her responsible for the mixer.
She knows the knobs well now, 1- 10 for mixing speed, higher number indicates faster speed.
I put butter and sugar in the mixing bowl and tell her 2 !
Then increase speed to 6 !
Reduce to 2 again! or whatever. . . .
She follows my instructions diligently and while I'm busy with other stuff (taking pictures :D ), she'll watch the mixing.
Oh ! She's more than happy to lend a helping hand :
