Is this too mean for punishment?

My hubby and I have decided that our son would get to open his presents on Christmas like normal but not get to play with them that day. Our son has put sunscreen on his bathroom floor, torn wall paper off of a wall, broke and ornament and didn't tell anybody while leaving gl on the living room floor and lied about it when we tried to figure out where the glitter came from (big no no when there is a baby in the house), and a few other things. Taking his toys away and no tv and the normal things just don't seem to be working. My hubby wanted me to take all the toys back but I suggested this. Now I told my mom and she said ok without any problems with it what so ever. BUT MIL on the other hand paused for a few seconds and said ok but then would not say anything else afterwards on her way out the door. I just want to ask her what she would have us do but I have seen the products of her parenting and really don't think her parenting style would do any good what so ever. Do you guys think it's too mean? What would you have done? Have any of you done anything similar? I see it as it's not like he doesn't get anything, and really there is no law saying that we as parents even have to buy Christmas presents for our kids so it's not like he's being deprived. He gets EVERYTHING he needs and then some.
