Short background, I train at home. My 5 year old daughter has a "weight set" (styrofoam toy weight bench) and likes to work out with me. When im done, naturally first thing I do is come in and make a shake.

She's always asking if she can have one, cause she worked out too, and she wants to be big and strong like me. (Kids say the darndest things)

Would there be any reason its not ok, to get one of those small blender bottles and mix 1/2 a scoop of protein powder in with her milk for dinner? (We typically eat right after workout).
