I'm strong!

Yesterday I was busy making a menu in the dining room when I heard my daughter give out a strangled sounding laugh. When I turned around I saw my 4 year old in his super hero costume standing on the couch, Holding my 1 year old daughter by her feet above the floor... I screamed and ran over to grab her before her head hit the floor. Then demanded to know why William thought that he could do that to his sister. William looked at me and said; "But mommy, I'm so very strong!" Boys!!!
