When should I expect budding and is it going to gradually happen or out of nowhere?

There's no precise timetable on when budding will occur. I would estimate somewhere in the range of a few months. I would say it's more of a gradual process than a sudden one.

Prior to budding, you'll likely experience some fat redistribution to your breasts. You may also experience some soreness, tingling or other growing sensations in your breasts during this time.

Also Budding can happen in an On & Off Fashon for some.

BTW Like the new Avatar Flame.
