Good for you for managing all that is going on in your life. 3 small children would have me huddled in a sweaty, whimpering ball.
The grand is about the size of a credit card on it's face and about as deep as a pack of cigarettes (92mm X 44mm X 24.25mm). It holds 6ml of juice and there is a 3rd party bottle mod you can do to take that volume to 9ml.
At 1.0 ohms, a 18650 should last you most of the day. If bat life is a feature/concern for you, this would be another reason to look at the grand over the mini.
The mini holds 3 ml, and uses a 18490 battery which (of course) would last you less time.
