When Does A Baby Develop Fingers?

One of the most fascinating things about human development is witnessing how a tiny, helpless baby transforms into a fully-formed, functioning human being. From the moment of conception, the cells in a growing embryo begin to divide and differentiate, eventually forming all the different organs and appendages that make up the human body. But when does a baby develop fingers, and how does this process unfold?

Weeks 6-7: The Formation of Limb Buds

Believe it or not, the basic structure of a baby’s fingers begins to form very early on in pregnancy – as early as 6-7 weeks after conception. At this stage, the embryo has just started to develop limb buds, which will eventually become arms and legs. These limb buds are made up of a group of cells that will go on to form the bones, muscles, and skin of the arms and hands.

Weeks 8-10: The Emergence of Fingers

Around 8-10 weeks after conception, the limb buds begin to separate into distinct segments, which will become the fingers and toes. At this point, the hand itself is still quite small and rudimentary, and the fingers are not yet fully formed. However, over the next few weeks, the fingers begin to elongate and differentiate, with the thumb appearing first and the pinky finger last.

Weeks 11-14: Fine-Tuning the Fingers

By 11-14 weeks after conception, the baby’s fingers have become much more refined and fully-formed. The individual bones in each finger have started to ossify, or harden, and the skin on the fingers has begun to thicken and develop fingerprints. At this point, the baby is fully capable of grasping onto objects and even sucking its thumb!

Weeks 15-20: Growing and Developing

Over the next several weeks, the baby’s fingers continue to grow and develop, along with the rest of its body. By around 20 weeks, the fingers are long enough to reach the opposite hand, and the baby can start to explore its environment by touching and grasping anything within reach. It’s also around this time that expectant parents can find out the sex of their baby through ultrasound – and sometimes even get a glimpse of those tiny fingers waving hello!


So, when does a baby develop fingers? The process begins very early on in pregnancy, with the formation of limb buds around 6-7 weeks after conception. Over the next several weeks, these limb buds begin to differentiate into fingers and toes, with the fingers becoming fully-formed and functional by around 11-14 weeks. By the time a baby is born, its fingers will have undergone an incredible transformation – from tiny buds to fully-formed digits capable of grasping, exploring, and interacting with the world around them.

Frequently Asked Questions

Q: Can you tell the sex of a baby by looking at its fingers?

Q: Are some babies born without fingers?

A: Yes, in rare cases, babies may be born with a condition called ectrodactyly, which causes them to be born without one or more fingers. However, with modern medical technology, it’s often possible to treat this condition and help affected babies lead normal, healthy lives.

Q: How can I encourage my baby’s finger development?

A: Simply allowing your baby to explore and play with objects of different shapes, sizes, and textures can help promote their finger development. As they grow and develop, you can also encourage them to practice grasping, pointing, and other fine motor skills by playing games and doing activities that require hand-eye coordination.

Q: When do babies start to use their fingers to feed themselves?

A: Most babies will start to use their fingers to feed themselves around 7-9 months of age, as they begin to develop the ability to grasp and manipulate small objects. However, every baby develops at their own pace, so don’t worry if your little one takes a bit longer to master this skill!

Q: Can babies hurt themselves with their own fingers?

A: While babies are generally not strong enough to hurt themselves with their own fingers, it’s still important to supervise them during playtime and make sure they’re not putting anything dangerous in their mouths or eyes. It’s also a good idea to keep sharp objects and small items that could be swallowed out of reach.
