My son just turned 2 months old and is getting his 2 month shots. In August he will be meeting his cousin and his cousin is 3 and has all of his shots as far as I know. Will it be safe to let them come in contact? I don't think he will be sick, so I doubt my son will get sick. I just want to know if it's a good idea to let them meet or should we wait longer? Sorry if this is a dumb question.
