I have a question about after care of a pediatric heart recipient. My 2 year old granddaughter has had her new heart for 6 months and all is going well. The whole family is very careful to avoid any contaminant that could get her sick. Recently, I (not thinking) agreed to babysit some newborn puppies and now I want to go see my babygirl. My question is, how do I know if it is safe to be around her after being around the puppies? I might know better how to answer that if I knew the risks that being around puppies creates.
