Congestion and cough?

Alex

Hello! My 15 month old caught a cold from her dad last Wednesday night. So over a week. She had her 15 mo appointment Tuesday and he said she looked and sounded great and doesn’t have a fever. But I’m like how long does this last??? She’s acting totally normal just so congested and runny nose and a cough! Experience? Help? First time mom and this is the first time she’s been sick!
