Your baby is now on a regular sleep cycle, including REM sleep, and the brain activity patterns resemble those of a newborn.

Development at Week 27

At 27 weeks, your baby's brain is developing complex patterns of activity and the nervous system is maturing rapidly. The lungs are capable of breathing air if birth were to occur now, though significant medical support would still be required. This is the final week of the second trimester — a major pregnancy milestone.

Next week

At week 28, your baby will be the size of a Eggplant.
