While she never shares this with him and never quite sees herself through his eyes, the realization that Mike's feelings are real is there despite it being dangerous to act on said knowledge lest he be totally ruined by excessive sympathy.
What isn't there is the realization that her need to withhold praise because she thinks doing so will make him into a praise-craving monster who gloats over not a heck of a lot has the revenge affect of making him into something of a monster who craves praise and tends to gloat about something he never got much. You see, if he had been given credit when it was due instead of being told to be humble, he'd know how to cope with praise and when to expect it and not be the smarmy jackass we know and loathe. Instead, we have a dick who acts like a malicious jerk whenever someone actually pays him a compliment. Ah, well. At least she does have some awareness that children just might have feelings; that puts her one up on Phil and John.
