However, there are certain milestones in fetal development that doctors use to determine whether a baby is developing correctly or not.

First Trimester
During the first trimester, which lasts from conception to week 12, your baby undergoes rapid development. By the end of the third week, your baby’s neural tube, which will later become the brain and spinal cord, begins to form. By week five, your baby’s tiny heart starts to beat, and by week six, their arms and legs begin to form.
By week eight, your baby’s major organs have formed, and they can even start to move around in the amniotic fluid. By week ten, your baby’s fingers and toes are fully formed, and by week 12, your baby’s sex can be determined. At this point, your baby is about the size of a lime and about two inches long.
Second Trimester
The second trimester, which lasts from week 13 to week 28, is a period of rapid growth for your baby. By week 16, your baby’s muscles and bones have developed enough for them to make small movements, which you may be able to feel as flutters in your belly.
By week 20, your baby’s eyebrows, eyelashes, and nails have formed, and they can now hear sounds outside the womb. By week 24, your baby’s lungs have developed enough that they could potentially survive if born prematurely.
By week 28, your baby is about the size of an eggplant and weighs around two and a half pounds. At this point, your baby’s brain is rapidly developing, and they can even dream. Your baby’s skin is also becoming less translucent, and they’re starting to look more like a newborn.
Third Trimester
The third trimester, which lasts from week 29 to week 40, is when your baby puts on the most weight. By week 32, your baby’s bones have fully formed, and they have a much better chance of surviving if born prematurely.
By week 36, your baby has likely settled into a head-down position in preparation for birth. And by week 37, your baby is considered full-term, which means they’re fully developed and could be born at any time.
By week 40, your baby is about the size of a watermelon and weighs around seven and a half pounds. At this point, your baby’s organs are fully developed, and they’re ready to be born.
The Bottom Line
So, how many weeks is baby fully developed? While a baby’s development is a continuous process, doctors typically consider a baby to be fully developed at around 37 weeks. However, it’s important to note that every baby develops at their own pace, and some babies may need more time to fully develop.
If you’re pregnant, it’s essential to attend all of your prenatal appointments to ensure that your baby is developing correctly. Your doctor will monitor your baby’s growth and development and let you know if there are any concerns.
Frequently Asked Questions
1. Can babies be born fully developed before 37 weeks?

3. What are the signs that a baby is fully developed?
There are no specific signs that a baby is fully developed, as every baby develops at their own pace. However, if you attend all of your prenatal appointments and your doctor does not express any concerns, it’s likely that your baby is developing correctly.
