Coughing

Mia • M O M M Y 💕

My son is 16 weeks and has been sick for 6 weeks and had a horrible cough for 2-3 weeks. His doctor said it’s allergies but idk why it hasn’t gone away. It’s just getting worse and worse. We have tried cough syrup and it doesn’t work at all.

What is this and what can we do to help him? He’s too young for allergy medication
