Baby's Development

Your baby's eyes are opening for the first time since fusing shut early in pregnancy. While there's nothing to see in the dark womb, this is an important developmental milestone, and your baby can now blink.

The lungs continue maturing, developing more of the surfactant needed for breathing after birth. Your baby is also developing a regular pattern of waking and sleeping, though it won't necessarily align with your own schedule.

Yes, mild breathlessness with exertion is common as your growing uterus puts pressure on your diaphragm and your body works harder to supply oxygen to both you and your baby. Sudden, severe breathlessness should always be checked by a doctor.
