Just like her husband, she does not possess any magical abilities whatsoever. It is unknown what her occupation is and until then, it can be assumed she stays home and takes care of the house. She is often seen waking the kids up for school, at evening family dinners, at different events or parent-teacher gatherings.
She is friendly and easy-going but stern and demanding when needed, such as when denying Ray Ray different bank cards or when expecting June to go to school despite June faking being sick. She sees through most of her kids' ruses and moods and thus could probably find out about June's double life fairly easily if it weren't for Monroe, their family's dog, freezing her or dusting her memory.
In Party Monsters, she asks Michael why his family "always eats like they've been starving on an island?" so it can be surmised that she has a snark level as great as her kids and possibly greater than that of her husband's. These snide remarks are usually said under the breath while the other character is not paying attention or is too oblivious but she simply says it out to her family members freely.
She has been seen being friendly with Ophelia's mom so it can be concluded that the two could possibly be friends either through their daughters' friendship or simply from knowing each other from their daughters' school. She also seems to be good friends with Roger's mom but this might be more due to both their husbands sharing a work place. In Feets Too Big where they share an episode, she sees Mrs. Radcliffe make a large dinner out of a travel pack with zero effort and immediately remarks Dennis to not even look that way when he notices it.
