Baby Development
The baby's muscles and lungs are continuing to mature. The baby is getting plumper as fat accumulates under the skin. The brain can now control primitive breathing and body temperature. The bones are fully developed but still soft and pliable. The baby is running out of room and movements may feel different - more rolls and stretches than kicks.
Week 29 Highlight: Your baby's brain is developing so rapidly that their head circumference is increasing by about 1.5cm this week alone!
Common Symptoms
Tips for Week 29
