Dry cough, no cold

[Marshmallowflump22]

does anyone know what I can do for a dry cough at night for a 3 year old. The last three nights she has been awake in the night for a couple of hours coughing. No cold, just a dry, tickle cough. I have tried honey, tixy lix and so far nothing seems to work. Does anyone have any ideas please?

Have you tried a steamy to help relieve it

I haven’t no, what is a steamy please? Thank you.
