Out of the goodness of my heart I let my sons dad take him for the day. I told him don't give him formula it makes him sick unless you get a certain kind take his stomach can tolerate. My son has tummy problems like me of course. He called me yesterday saying he just got my son formula and gave it to him.., twice. Who has sat up from 1-8am? Me. Changed his diapers from the diarrhea? Me? Cleaned up his throw up? Me. If I say not to do something it's for a reason.
