Jericho (recently turned 3) is a toughie when it comes to discipline. It's often clear she knows she's done wrong, but any form of discipline - from firm reprimand to spanking (yes, we spank. *gasp*) - results in tears of either deep sadness, or extreme madness. We are often at a loss with her.
Today she was scolded for playing with something she shouldn't. I said softly, but firmly, that she wasn't to do that. She hid under my desk. Normally I wouldn't allow it (hiding/pouting), but I did. About 2 minutes later she came out, gave me a hug, and said "sorry". I nearly fell off my seat!! Maybe a few minutes to stew is just what she needs?? I guess time will tell... :)
