Re: S/o what discipline works in YOUR family???
DD2 is almost 8 and we "ground" her by not allowing her to visit with friends and no access to any type of electronics. Very rare that we have to discipline her anymore.
DD3 is 2 and we use time-out (2minutes) if reasoning doesn't work (she is VERY verbal, so oddly, we can actually reason with her verbally sometimes!).
