Wilfreda needs to learn the phrase "everything in moderation."
Obviously a repeat offender.
Mr. Peabody seems like a very patient man, which unfortunately may work against him when dealing with the precocious young witch. Wilfreda clearly isn't tuned in to things like nuance and subtlety, but if he's a nice older gentleman he can probably be direct without resorting to being mean, though like Ms. Mimi I'm sure he'll be a bit frustrated by the end of their encounter. If that would bother him then he'd better not make the mistake of calling Miriam too.
