Pregnancy week 24
This week your baby is about the size of an ear of corn — around 30 cm and 600 g.
Your baby this week
Your baby reaches an important milestone this week, as the lungs begin producing a substance called surfactant that will help the air sacs expand and support breathing later on. The face is nearly fully formed, and the skin is gradually gaining color and smoothness as fat builds up. Hearing continues to develop, and your baby may respond to familiar sounds with a movement or kick. Sleep and wake cycles are becoming more established.
Your body this week
Your belly may feel bigger and heavier now, and you might sense some pressure or discomfort in your lower back. Increased appetite is common at this stage, along with mild itching of the belly skin as it stretches. You may also notice your feet swelling more by the end of the day.
Tips for this week
Around this time your provider may suggest a gestational diabetes screening, a routine test that helps reassure you about your health and your baby's. Keep up gentle activity like short walks to support digestion and circulation. Moisturize your belly regularly to ease itching, and if it becomes very intense, let your healthcare provider know.
