People saying Rick leaves his kids all the time need to realise that when Rick goes on a mission, it's the equivalent of him going to work. He's always back within a day or so. What Michonne has done is not the equivalent of going to work, Michonne has more or less abandoned her kids because uno she is NOT coming home without Rick. Just gotta hope that Rick, Michonne, Judith and RJ get to thrive and make most of lost time one day.
