If you are not a citizen of Ghana yes you need a Visa. Green card is just for the US has nothing to do with Ghana.
Also does your baby have a US passport? or what country was your child born.
As far as shots you should call the health department that does travel shots and ask what is best for a 6 month old. There are no shots that are required just so you know. Just advised like yellow fever, DTP.
