Night time cough can be because of tonsils adenoids postnasal drip due to infections and allergies sometimes asthma. Requires evaluation and advice.

It's normal only it  could be Post nasal drip, gastroesophageal reflex,  adenoids

Greetings Nighttime cough in a 3-year-old can have several causes and often requires a professional evaluation. The symptoms described are consistent with conditions such as post-nasal drip from a cold or allergies, childhood asthma which frequently flares at night, or gastroesophageal reflux. You should monitor for "red flags" like difficulty breathing, wheezing, or a persistent fever. To help your daughter, you might try using a humidifier, ensuring she stays hydrated, or slightly elevating her head during sleep. Since the cough is persistent and affecting her rest, please consult a pediatrician

A cough that occurs mainly at bedtime, during sleep, and early in the morning while your child is otherwise active and well during the day is often due to post-nasal drip from allergic rhinitis, enlarged adenoids, or airway hyperreactivity/asthma rather than a simple seasonal cough. While occasional coughs can occur with weather changes, persistent night-time cough for more than a few weeks should be evaluated by a pediatrician. Watch for associated symptoms such as snoring, mouth breathing, recurrent colds, wheezing, or exercise-induced cough, as these can provide important clues to the underlying cause.
