For many new parents, the first year feels like an endless cycle of colds, fevers, and doctor visits. You may wonder, “Why is my baby always sick?”
In most cases, this pattern is completely developmentally normal.
The first year is the immune training year. Exposure builds defense.

💬 Parent Reviews
This article really reassured me. My 8-month-old kept getting colds and I was very worried. Understanding immune development helped me stay calm.
Very clearly explained. Our pediatrician said the same thing, but this made it much easier to understand.
As a first-time mother, this helped reduce my anxiety a lot. The hygiene balance section was especially useful.
