Finally Figured it Out

I finally figured out how to paint let Kaeley paint with tempura paint and still have Nathan awake under the same roof:
Prep:
1. Tape finger paint paper over entire surface of table
2. Fill the sink with warm soapy water
3. Have children, especially Nathan, either naked or still in pajamas
4. Each child has their own paper plate full of paint

Clean:
1. Both children, especially Nathan, goes directly into the bathtub
2. Art work dries where it is
3. Everything that has been touched by Nathan goes into filled sink
4. Start laundry with Nathan's pajamas in them.

See? Stress free.
