Full sleeve tattoo?

A few days ago I had waddled upstairs to prepare food for my starving children. I was feeling pretty ambitious because I decided to whip up some mac & cheese. Mac & cheese has become the rare treat around our house because it either requires me to stand on my feet for a long time or sit down and get back up, something just as difficult. While I was upstairs engrossed in this labor of love for my children, Turner comes sprinting upstairs. "Mom, mom Grandma is on the computer." The main way I communicate with my parents in Austria (who are on a mission there for the rest of the year) is by Skype. We love it! So I lumbered down the stairs in anticipation of seeing my mommy. As I entered the family room I see my 2 year old son in the corner coloring. After he had filled his paper he decided that his body also made a nice canvas. I picked him up and proceeded to chat with my mom. She noticed his nice handy work. My children have become a little wild as my physical abilities have become limited. I decided it wasn't a big deal and we would just wash it off after lunch. During lunch I noticed that my son, who still eats with his hands a lot, was now eating blue mac & cheese. I also noticed that it looked as if he had a full sleeve tattoo! I thought it was quite funny. Especially since my husband is VERY anti-writing on yourself. He feels it promotes a desire for tattoos. I on the other hand usually use my hand instead of post-its. (We all need to do our part of the environment right?) I am thankful for non-toxic art supplies!
