COVID test for infants

My doctor recommend I get a COVID test for my daughter but when I called they told me the nasal swap was way to big for her nose and could be a liability & im not comfortable with that so I called the doctor and said can I just keep her for the remaining 2 weeks or I’ll just get tested and the receptionist kept saying well she recommended so as if I HAVE to do it.. & that the probably most likely won’t feel it, anybody has any experience with the COVID testing for babies ?
