How would i know if my baby has strep throat if all i see is the stuffy nose?

Have it tested: Babies do get strepa disease & it may be more nasal than throat & can be anal sores. The only way to verify is thru teating.A quick test that takes a few minutes is available in many primary care offices.If your baby had a known exposure & is showing symptoms a visit is worthwhile.You do have several days to treat before strep might trigger complications. No fever?No change in behavior? Doubt it.
