If I could just say to my girls "Jane, you will want to do A, B, and C. Never go near D and don't even think about E." Wouldn't it be wonderful if they would listen and follow my instructions exactly? Fortunately, they are individuals who want to explore and discover things on their own. Most likely they will forget about A and B, maybe do C, try out D and go straight for E. And that's OK. Throughout that process they will grow from their mistakes, just as I have grown from mine.
I've decided the best thing I can do for them is to fervently teach them right from wrong and then allow them to make their own decisions. They will love me for it, and I won't give myself an ulcer trying to control something I have no business controlling. So when my 2 year old is adamant about wearing bright orange and black cat printed pants with a blue and yellow flower shirt, I'll let her. Then I'll take a picture and post it on her Facebook page when she is 16.
