I'm very fortunate.  I just finished nursing school, and he totally pitched in with EVERYTHING.  I know my being in school was almost as hard on him as it was for me.  My friends are all really jealous.  On his days off he would take the boy (16 months old) and the girl (11 yrs old) and disappear so I could study.  When we were both home, you name it, he did it.  Including washing the dirty diapers.    My mom even brags about him to all of her friends!
