I don't know much about use of chlorhexidene shampoo for humans. I know that it is definitely available for use in animals and is great at helping to treat infections. I won't get it completely. Antibiotics are still needed. I would assume that a product like this would have to be a prescription. I know that it can also be very drying to the skin - it's how it works. I'm not sure for use on a 2-year old but would definitely talk to your pediatrician before trying it.
