When do babies develop fingernails and toenails? Your baby’s fingernail and toenail beds begin to form at week 11 of pregnancy with the nails themselves starting to grow at week 12.

Key milestones in fetal limb development

First, the cells of the embryo (called embryonic stem cells) multiply and develop. They become the hundreds of different types of cells needed to make a whole human body. Your baby’s major organs and body parts begin to take shape. The placenta forms during the embryonic stage.

Baby Chanco is two years old and already has 388,000 followers on Instragram.

It takes most babies months to start sprouting their first hairs, but Baby Chanco was born in Japan in December 2017 with a full mane. Seven months later, she’s become known for it the world over.

The reason for it is most likely genetics — if you or your child’s other parent had a lot of body hair as a toddler (or someone in either of your families did), your toddler simply “inherited” the body hair. Body hair is often darker, and therefore more noticeable, on children with darker complexions.

Lanugo is the hair that covers the body of some newborns. This downy, unpigmented hair is the first type of hair that grows from hair follicles. It can be found everywhere on a baby’s body, except on the palms, lips, and soles of the feet. Most fetuses develop lanugo around the fourth or fifth month of pregnancy.

The follicles that grow while they’re in the womb form a hair pattern they’ll have for the rest of their lives. New follicles don’t form after birth, so the follicles you have are the only ones you’ll ever get. The hair is visible on your baby’s head and may grow quickly or slowly during the weeks leading up to birth.

Turns out, hair loss can strike at any age — including infancy. According to the American Academy of Pediatrics (AAP), most babies lose some — or even all — of their hair in the first few months of life. And it’s completely normal.
