My Vocab Practice:
Nurse.
My best friend has retired as an NICU nurse a few years ago.

Nutrition
The doctor told me I was not getting enough nutrition from my food.

Nutrient
We all must eat a balanced diet to get the nutrients we need to maintain good health.

Nurture
It's a good idea to nurture your children in such a way as not to smother them with over protectiveness and stifling their minds from growing and learning new things.
