To ensure your baby's development during pregnancy, it's crucial to maintain a healthy lifestyle. Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins provides essential nutrients. Regular prenatal check-ups with your GP will help monitor your baby's growth and identify any concerns early. Engaging in moderate exercise can also promote overall health, but always consult your healthcare provider. Additionally, avoid harmful substances like alcohol and tobacco. Staying informed about your baby's developmental milestones can help you understand what to expect during each trimester.
