So my 3-year old comes out and asks me to tuck him in for the Nth time tonight - so I happily do it... Both our boys (3 and 5) share the same bedroom as we turned the other into their playroom. The 5 year old seems asleep and I am trying to keep the 3 year old quite when, from under the covers, the 5 year old says "Yum!". What? What's yum? "My boogers..."
