Your spiritually adopted baby’s development at approximately 8 weeks:
Your baby is moving! The movements start at about 7 to 8 weeks and are visible on ultrasound. You won't feel your baby move until sometime between 16 and 22 weeks, though. Your baby's respiratory system is forming. Breathing tubes extend from your baby's throat to the branches of their developing lungs. A network of nerves is spreading through your baby's body, making connections not only with each other but also with muscles and other tissues, as well as organs like the eyes and ears!
