I don't think I would give my child Silk, just out of personal choice. Silk is a relatively new product. We really don't know how good/bad it can be for us. To much soy is a BAD thing.
being that it has a 5th channel. It is a mono channel, there is no bridging it. To bridge a channel, it will have to have 2 channels.
You should write to Chanel for clearance to do so, you don't want to be sued if they find out. Since the jewelry looks exaclty like Chanel, it is trademark infringement. You will be sued.
