What's happening with baby
Around week 30, your baby is continuing their incredible growth spurt, now roughly the size of a cucumber. Their brain is developing rapidly, forming more convolutions and grooves, which increases its surface area. This is a crucial time for neurological development, laying the groundwork for all the amazing learning they'll do once they arrive.
Their lungs are also maturing significantly, producing more surfactant, which is essential for them to breathe easily after birth. While still developing, these tiny lungs are getting ready for their big debut. Layers of fat are continuing to accumulate under their skin, helping with temperature regulation once they're outside the womb. Their bone marrow is now fully responsible for producing red blood cells, a role previously shared by other organs. You might also notice more distinct movement patterns, as they're getting stronger and their space is becoming a bit more limited.
What you might be feeling
This week often brings a mix of excitement and increased physical discomforts. Sleep can become a real challenge, as finding a comfortable position, frequent bathroom trips, and your baby's active periods can interrupt your rest. You might also notice Braxton Hicks contractions becoming more frequent or intense. These are your body's way of practicing for labor, and while they can be surprising, they're generally not painful or regular.
Fatigue can also creep back in, a natural response to the demands of late pregnancy and disrupted sleep. You might feel more pelvic pressure as your baby settles lower, and some people experience mild swelling in their ankles and feet. Emotionally, you might be feeling a heightened sense of anticipation, perhaps mixed with some anxiety about labor, birth, and parenthood. It's a lot to process, and all these feelings are completely valid.
