Watching your little one grow and change can be an exciting and sometimes overwhelming experience, but understanding when different developments are likely to occur can help ease some of those worries. In this article, we’ll go over when babies typically begin to develop various body parts and what you can expect to see as your baby grows.

When Do Babies Develop Their Arms and Legs?
Babies start developing their arms and legs very early on in the pregnancy, with tiny buds forming around 4-5 weeks after conception. These buds will eventually grow into arms, hands, legs, and feet, and by the end of the first trimester (around 13 weeks), the baby’s limbs will be well-formed and moving around. By around 18-20 weeks, the baby may start kicking and moving their arms and legs more frequently, which can be felt by the mother.
When Do Babies Develop Their Eyes?
The eyes are one of the first organs to develop in a baby, starting around week 4 of pregnancy. By week 8, the basic structure of the eyes is formed, including the retina, optic nerve, and lens. However, the eyes won’t be fully functional until several weeks after birth, as the baby learns to focus and coordinate their eye movements.
When Do Babies Develop Their Ears?
Like the eyes, the ears start developing very early on in pregnancy, with the inner ear starting to form around week 3. By week 8, the baby’s earlobes are visible and the inner ear is fully formed. However, the baby won’t be able to hear until around 18-20 weeks, when the auditory system is fully developed.
When Do Babies Develop Their Teeth?
The first teeth start to develop in the baby’s jaw around 6 weeks after conception, but they won’t emerge until several months after birth. Most babies will start developing their first teeth (usually the bottom front teeth) around 6 months of age, although this can vary. By age 3, most children will have a full set of 20 baby teeth.
When Do Babies Develop Their Hair?
Hair follicles start forming on the baby’s scalp around week 14 of pregnancy, and by week 20, the hair is visible on ultrasound. However, the amount and texture of the hair can vary widely between babies, and some babies may be born with little or no hair. Baby hair growth can continue for several months after birth, with some babies not growing a full head of hair until well into their first year.
When Do Babies Develop Their Organs?
The major organs (heart, lungs, liver, kidneys, etc.) start forming very early on in pregnancy, with the heart starting to beat around week 6. By around week 10, all of the baby’s major organs are formed, although they won’t be fully functional until several weeks or months after birth. The digestive system, for example, doesn’t start working properly until after the baby is born and starts taking in breast milk or formula.
When Do Babies Develop Their Brain?
The brain is one of the last organs to develop in a baby, starting around week 3 and continuing throughout the pregnancy. By around week 25, the baby’s brain is developed enough to start controlling some body functions, such as breathing and heartbeat. However, the brain will continue to grow and develop rapidly after birth, with the first few years of life being particularly important for brain development.
In conclusion, a baby’s development is a complex and fascinating process that starts from the moment of conception and continues throughout childhood. Understanding when different body parts and organs typically develop can help new parents feel more confident and informed as they watch their little one grow and change.
