Hi @bac10, welcome to Connect. I can see why you are concerned. I know from experience that kids and toddlers, especially those that go to daycare, can be frequently sick with all sorts of different bugs. I also had a toddler go through hand, foot, and mouth, as well as what were unconfirmed absence seizures for a brief period. I can't imagine having to deal with the frequency of infections and illnesses that you having to.

Here is a video Q&A with Angela Mattke, M.D., who hosts a regular series called Ask the Mayo Mom, about Common Infections in Children and When to Worry It Could Be Something More, https://youtu.be/oNGrCIlJpEQ.

@bac10, while it is encouraging to here that your daughter does not present with an immunodeficiency or autoimmune disorder, I can understand why you are frustrated without a diagnosis or reason for all of the infections. While I am not a medical professional, has one of your providers talked about environmental factors as being a possibility? Does your daughter go to a daycare where other children are frequently sick?
