I'm usually giving Tom a bath.(2) At nine in the morning Iím usually bathing Tom.That is a more suitable explanation for sentence #1.(1) At nine in the morning Iím in the habit of bathing Tommy. I usually start at nine because Tommy is always very hungry in the morning and wants to have breakfast soon after he wakes up.That's fine.(2) The bathing began before the point in time and probably continues after it. It is still a habit [as I understand it], but with (2) I want to point out that at nine in the morning the action is going on.
