By week 40, the timeline you’ve been tracking is officially here. If you were to weigh your baby right now, she would likely come in at about 7 pounds. Her length from head to toe sits at roughly 21.5 inches. It is a solid size. Her fingernails and toenails have finished their growth. They are fully formed.
She is preparing for the outside world. The lungs are testing their function. This is practice for the first breaths she will take independently. She probably won’t grow much longer. The frame is set. She might pick up a few more ounces before delivery, but vertical growth has stalled. If you deliver at this specific point, she is not premature. She is full-term. The odds of her being a healthy weight and size are very high.
Space is at a premium. The uterus is packed tight. This lack of room does not mean she is resting. She is still moving. The movements you feel now reveal her strength. You might notice her head settling downward. It is burrowing toward your pelvis. This is the engagement process. It often happens as labor approaches.
Keep tracking the movements. You have likely become an expert at counting kicks and punches by now. It still matters. You need to ensure the baby remains active. Sudden changes in movement patterns can be a sign of distress. Do not ignore a decrease in activity.
The Induction Question
Weight and size play a role in delivery planning. Your doctor may discuss inducing labor at 40 weeks. This is a common conversation. It is not always a given. The decision often depends on the estimated size of the baby. If the baby is large, some physicians may worry about a vaginal birth. They might suggest induction to avoid complications.
Other doctors have different protocols. Some allow you to go one to two weeks past your due date. They will wait before intervening. There is no single rule for when to induce. It varies by provider. It varies by patient history. It varies by the baby’s position and size.
If your doctor suggests induction, ask about the reasoning. Is it because of the baby’s size? Is it a general policy? Understanding the “why” helps you decide if you are comfortable with the plan. Every pregnancy is different. Some babies drop earlier. Some stay higher up. The timing of labor is unpredictable.
You are at the end of the journey. The body is preparing. The baby is ready. What happens next is a mix of biology and medical guidance. Stay in touch with your care provider. Monitor the baby’s movements. Be ready for labor at any moment. The clock is ticking, but the countdown feels different now. It is not just time. It is presence.
