HIPPA, children's medical records and rights to privacy under TX state law

privacy acts regarding children: My child received a unsigned delivery from a florist while in the hospital. When I called the florist to ask who sent it, they refused to tell me due to a privacy law.
The card attached also contained other personal info about my child.
Does the privacy laws differ when pertaining to children and how could I find out who sent it. - Is this your question? Add additional information
