Yeah, she's fairly sure that I could even play it with them just never taking him in to the doctor. She didn't think there were permission slips for sports and such (which the doctor she worked for at least required a well check within a year or less to sign) and in a small town like that... a parent might only take their kid in when needed and only got vaccines if they wanted them... Also, M+J might not even need any doctor's check for a birth certificate if 'the cousin' had a home birth. Funny aside, my great grandma was a home birth and they didn't get her birth certificate until a year later... and whoever filled it out put the filing year not the birth year on it. To her dying day she claimed the year on her birth certificate for her real age, heh. That was pre-WWI though.
