First, if you are ever involved in such an unfortunate situation, you have my deepest sympathy. The answer to the question is yes. If your child dies due to the negligence of others you can bring a claim.
The Florida wrongful death act lays out the types of damages that can be recovered in this specific type of case and it depends on whether your child was injured in an auto accident, or in a medical malpractice incident, and so forth. For the specifics as to your child wrongful death claim, you need to seek the advice of an attorney who can answer these questions for you.
