Baby Development
Your baby is starting to have rapid eye movements, and ridges are forming in the palms of the hands and soles of the feet that will create the foundation for fingerprints and footprints. The lungs are also starting to make a substance called surfactant, which allows the air sacs in the lungs to inflate and keeps them from collapsing and sticking together when they deflate. If born preterm, some babies this far along in pregnancy may be able to survive outside the uterus.

During week 23 of your pregnancy, you may notice some changes in your body's metabolism as it adjusts to support your growing baby. This phase is marked by natural metabolic adaptations where your body becomes highly efficient at storing energy, laying the groundwork for the essential nutrient supply your baby needs in the following months. You might feel an increased tendency to store energy as maternal fat, a typical part of pregnancy that helps prepare for breastfeeding and other demands. It's also a good time to focus on healthy eating habits, emphasizing nutrient-dense foods like fruits, vegetables, whole grains, lean proteins, and healthy fats. These foods supply the necessary vitamins and minerals important for both you and your baby. Continuing with small, frequent meals can help maintain energy levels and prevent blood sugar dips. Staying hydrated is crucial, so keep up your water intake to aid in overall well-being and potentially ease any constipation concerns. Incorporating moderate physical activity, such as walking or prenatal yoga, can also boost your mood, increase energy, and support a healthy pregnancy. Always listen to your body and rest when needed, ensuring you balance activity with relaxation during this exciting time.
