If this is a wild baby your best option is to find a wildlife rehabilitator to take over its care.
This site may help you find one

most areas its illegal to keep a wild animal as a pet. You may also find it hard to locate a vet to work with as many will not treat wild animals. The risk from rabies is one reason.
You can see a list of vaccines used in this species here

You will need to treat for worms and you can read about the raccoon worm that is a health hazard here

You can raise the racoon on either cat or dog food and I'd suggest a daily pet vitamin mineral tablet be a part of that too.
Here is some more info

Be aware at sexual maturity raccoons tend to cease being pleasant about handling or confinement. They are very cute but they have their own priorities as they mature. I can tell you from personal experience they can bite through a layer of heavy denim with leather under it and two layers of leather gloves and still bite through fingernails and joints. I expected my orphan to eventually bite me but i was surprised at how good she was at it. Its been about 35 years now but I can still see the scars. Not her fault at all it was just she was not designed to be a pet.
The best thing for these animals if orphaned is to have a wid life rehabilitator get them ready for life in the wild.
Hope this helps you!
