My preferred definition for status is "the ability to control (or influence) the group", which as a special case includes the ability to control yourself. Children are in general far more protected than adults, but a lot of that protection comes at the cost of having harsh restrictions on your freedom, so under this definition children would be considered to be low-status. (You could also word this as "status is the amount of optimization power you are allowed to exert". Hmm. I wonder this would be worth a top-level post.)

Women have historically had a number of restrictions on their ability to control themselves and the broader group. They didn't always have the right to vote or to spend money without their husband's permission, and to some degree they persist in having less sexual freedom, a smaller pay than males, be less likely to be found in positions of authority or to be taken seriously when in authoritative positions, be less likely to be found in prestigious occupations, and so on.
