At 12 weeks pregnant, you're likely eager to know what to expect as your baby continues to grow and develop rapidly. This period is crucial, with significant milestones achieved in fetal development. As an expecting mother, understanding these changes can help you better connect with your unborn child and make informed decisions about your pregnancy.
12 Weeks Pregnant: Baby's Size and Development
At 12 weeks pregnant, your baby measures approximately 2.5 inches (6.4 cm) in length and weighs around 0.25 ounces (7 grams). Although still small, your baby's major organs and body systems are functioning and developing rapidly. The pancreas starts producing digestive enzymes, and the liver begins producing bile. The kidneys are now functioning and producing urine, which is excreted into the amniotic fluid.
Fetal Development at 12 Weeks
During this period, your baby's development accelerates, with several significant milestones:
- The baby's skeleton changes from soft cartilage to bone.
- The digestive system starts practicing contractions, preparing for life outside the womb.
- The nervous system and brain develop rapidly, enabling your baby to respond to stimuli.
- The senses (eyes, ears, and nose) continue to mature.
