Babies' fingernail and toenail beds begin to form at week 11 of pregnancy, with the nails themselves starting to grow at week 12. By week 20, the nails are clearly visible and are soft and translucent. They harden and thicken during the third trimester but remain relatively soft and flexible at birth. While data on nail growth rates is limited, a 1959 study found that normal infants' fingernails grow on average 3.36 mm per month, while another study found the rate to be 3.47 mm per month. Interestingly, pregnancy can increase nail growth due to higher levels of growth hormones and a faster metabolism.

What You'll Learn
Baby nail growth rate
A baby's fingernail and toenail beds begin to form at week 11 of pregnancy, with the nails themselves starting to grow at week 12. By week 20, the fingernails and toenails are clearly visible, and they will harden and thicken during the third trimester. At birth, a baby's nails are still quite soft and flexible compared to older children's nails.
The rate of nail growth is largely dependent on age and which finger the nail is on. The middle fingernail tends to grow faster than other nails. On average, fingernails grow at a rate of 3.47 mm per month, while toenail growth is slower at 1.62 mm per month. In a 1959 study, the normal nail growth rate for infants was found to be 3.36 mm per month, while premature infants (weight 1150-1900g) had a growth rate of 2.55 mm per month.
Certain factors can affect the rate of nail growth. For example, illness, stress, and certain infections can decrease the rate of growth, while pregnancy can increase it due to higher levels of growth hormones and a faster metabolism. Additionally, keeping nails moisturized can help prevent brittleness and breakage.
Maintaining clean and trimmed nails is important for babies. Regular trimming can prevent dirt buildup under the nails, which can occur due to exposure to lotions, sweat, spit-up, breast milk, formula, and dead skin cells. If you accidentally nick your baby's fingertip while trimming their nails, rinse the cut under cool water and apply gentle pressure with a tissue.

Nail growth variation
The rate of nail growth varies across individuals and is influenced by various factors, including age, finger, health conditions, and pregnancy.
Age and Finger Differences: The speed of nail growth can differ depending on a person's age and which finger is being considered. Generally, fingernails tend to grow faster than toenails, with the middle fingernail often exhibiting the fastest growth rate among all fingers.
Health Conditions: Certain health conditions and external factors can impact nail growth rates. For instance, illnesses, stress, chemotherapy, infections, and drug use may slow down nail growth. In contrast, pregnancy can lead to increased nail growth due to elevated levels of growth hormones and a faster metabolic rate.
Individual Variation: There is inherent variation in nail growth rates among individuals. While the average fingernail growth rate for young adults is approximately 3.47 mm/month, with toenails growing at about 1.62 mm/month, these rates can differ across people due to genetic and environmental factors.
Premature Babies: Studies have shown that the rate of nail growth in premature infants (weight 1150-1900g) is slightly slower than that of normal infants, with a growth rate of 2.55 mm/month compared to the average of 3.36 mm/month for normal infants.

Trimming baby nails
Trimming a baby's nails can be a nerve-wracking experience, but it is important to keep them short and clean. Baby's fingernail and toenail beds begin to form at week 11 of pregnancy, with the nails themselves starting to grow around week 12. By week 20, the nails are clearly visible and have hardened and thickened, although they are still quite soft and flexible compared to older children's nails.
A baby's nails grow at a rate of approximately 3.36 mm per month, which is faster than the average adult rate of 1.9-4.4 mm per month. This faster growth rate is due to increased levels of growth hormones and a faster metabolism during pregnancy. It is important to keep a baby's nails trimmed to prevent dirt buildup under the nails, which can occur due to exposure to lotions, sweat, spit-up, breast milk, formula, and dead skin cells.
When trimming a baby's nails, it is best to do so while they are distracted, such as during feeding time. It is important to use proper trimming tools and avoid biting the nails into shape with your teeth, as this can introduce germs and make it difficult to see what you are doing. If you do accidentally nick the baby's fingertip, rinse the cut under cool water and apply gentle pressure with a tissue. Do not use a bandage or liquid bandage product, as the baby could put their finger in their mouth and choke on it.
Keeping a baby's nails clean is easier than trimming them and can be done with a gentle washcloth or baby nail brush. Overall, trimming and cleaning a baby's nails is an important part of their hygiene and can be done safely and effectively with the right tools and techniques.

Cleaning baby nails
Baby nails, or an infant's nails, grow at an average rate of 3.36 mm/month. Keeping your baby's nails clean and trimmed is important for their hygiene and safety. Here are some detailed instructions for cleaning your baby's nails:
Prepare the Necessary Tools
Before you begin, ensure you have the right tools for the job. You can use baby nail clippers with blunt, rounded tips, or small baby nail scissors. You can also use a nail file or emery board to gently smooth and shape your baby's nails. Electric nail files or baby dremels are other options, although some parents find them less practical.
Choose the Right Moment
The best time to clean and trim your baby's nails is when they are calm, relaxed, or sleeping. Some parents choose to do it while their baby is feeding, as they will be distracted and less likely to fidget. If your baby is very young and not yet mobile, their nails may not get too dirty, but it's still important to keep them clean and trimmed to prevent accidental scratches.
Clean the Nails
To clean your baby's nails, you can use a soft-bristled baby toothbrush or a baby nail brush. Gently scrub the nails while holding your baby's hands under water during bath time. You can also massage a small amount of Vaseline or baby oil into the nails, leave it for a while, and then wipe and wash it out. This can help loosen and remove any built-up dirt or grime.
Trim or File the Nails
After cleaning, you can trim your baby's nails carefully with the appropriate baby nail clippers or scissors. Be very cautious not to cut the baby's skin. Alternatively, you can use a nail file or emery board to gently shorten and smooth the nails. This method is generally considered safer, as it reduces the risk of accidentally cutting the baby's finger or toe.
Handle Accidents Calmly
Despite your best efforts, accidents can happen, and you might accidentally nick your baby's fingertip. If this occurs, don't panic. Simply rinse the cut under cool water, then gently wrap a tissue around the finger and hold it with gentle pressure for a couple of minutes. Bleeding should stop quickly, and it's important to resist the urge to put a bandage on the finger, as it may come off and pose a choking hazard.
Maintain Regular Nail Care
Baby nails grow quickly, so you'll need to trim or file them regularly. Fingernails may need attention at least once a week, while toenails can be cut a couple of times per month. Regular nail care will help keep your baby's nails short and reduce the risk of scratches or dirt buildup.

Factors influencing nail growth
Several factors influence the growth of nails in babies. Firstly, the growth rate of fingernails and toenails varies, with fingernails growing faster. In a study of young adults, the average fingernail growth rate was 3.47 mm/month, while toenail growth was 1.62 mm/month. This difference in growth rate between fingernails and toenails is also observed in infants, with fingernails growing at an average rate of 3.36 mm/month.
Age is another factor influencing nail growth. Generally, nail growth tends to slow down as people age, and infants have faster-growing nails compared to older children and adults. Additionally, the specific finger or toe also affects growth rate; for example, the middle fingernail tends to grow faster than other nails.
Maternal factors during pregnancy can also impact a baby's nail growth. Increasing levels of growth hormones, a faster metabolic rate, and the overall changes that occur during pregnancy contribute to faster nail growth in pregnant women, which may extend to the baby's nail growth in utero.
Other factors that can influence nail growth include illness, stress, and nutritional deficiencies. Illnesses, certain infections, and nutritional deficiencies have been associated with slower nail growth. On the other hand, stress and pregnancy can increase nail growth rates.
It is worth noting that while some beliefs and remedies surround speeding up nail growth, such as garlic application or increased protein intake, there is limited evidence to support these claims. Nail growth appears to be predominantly regulated by the body.
