Baby development at week 34
The central nervous system and lungs are maturing well. Babies born now usually do well with little or no extra help. The vernix coating thickens to protect the skin, and the fetus's fat stores are filling out the limbs and face. The fingernails now reach the fingertips. About the size of a cantaloupe.

What trimester is 34 weeks?
Week 34 falls in the third trimester. As a quick map: the first trimester runs weeks 1–13, the second covers weeks 14–27, and the third is week 28 through birth (a due date is set at 40 weeks).

The third trimester (weeks 28–40+) is about growth and getting ready for birth. Prenatal visits become more frequent, the baby gains most of its weight, and you'll watch for the signs of labour. Tiredness and physical discomfort tend to return as the due date approaches.
