My 2 year old daughter has had a persistent dry cough since her last cold.

Hello, thank you for your question!

The cough is often the last symptom to disappear after a cold, even several weeks later!

There is not much to give him, except to encourage him to drink lots of fluids

Often there is a little bit of nasal discharge that falls back into the throat. The best way to remedy this is with sinus hygiene using a saline solution like Hydrasense. This product can be used as often as desired during the day, and may help to reduce the cough

You should notice an improvement, even if gradual, every day

I hope this has been helpful to you, and if you have any further questions, please don't hesitate to ask!
