Cough is very common in children. It can be caused by a cold, infection, allergies, or irritation in the throat. While medicine can help, food and drinks also play a big role in easing symptoms. What your child eats can help reduce throat irritation, clear mucus, and support the immune system. At the same time, some foods can make cough worse. This guide helps parents understand what foods are best and which ones to avoid when a child has a cough.

My child recently had a cold with a throat full of phlegm. I've found that if she adjusts her diet appropriately, her condition improves quickly. However, if she doesn't avoid certain foods, her cough will linger for a long time.
