Confrontation about secrets w/ 4 yr old

[myboysmom]

My 4 1/2 yr. old son has started to become sneaky. He will do something he's not supposed to and get caught by someone else, then tell them not to tell me. He doesn't tell them not to tell Dad, or Gma, just not Mom. Like yesterday he said a cuss word in front of my 10 yr. old cousin, which he knows he's not supposed to, and I'm sure she told him that, but he asked her not to tell me. She did, so I talked to him about it. I wasn't mad, but we discussed it. Today, while in the bathroom supposedly washing up, he sprays his dad's shaving cream pretty much all over the counter, and his dad opened the door to see him with the razor in hand, I think. Well, apparently he told his dad not to tell me. So my question is:
Do I confront him about it? Or let him have this secret with his dad, since dad took care of it?

I would let him have it. As long as an authority figure takes care of it I think its fine. But I would talk to his dad about it and maybe have him the next time he pulls the whole "dont tell mommy" bit to maybe have a talk with him, maybe it will help coming from daddy and I would think its just a phase, and if I were you I would be happy, this means he doesnt want to disappoint you, not that he doesnt want to get into trouble because obviously you wont yell. So he just doesnt want to hurt you, which should be a compliment! Be proud of yourself, you did something right!
