Why do newborn babies have to wear little hats?

Newborns are often given a hat or cap when they are first born, and they wear it throughout their hospital stay. Newborn hats are also a popular clothing item at stores and on baby registries.


Humans lose a lot of heat through their heads, and hats help to keep the warmth in their bodies.

Change in Environment

Babies are used to being snuggled warmly in the womb. When they are born, they are pushed into the cold. The warm hats help them feel a little like they are still snuggled safely in the womb.

How Long Should They Wear Them?

According to Howard Reinstein, an American Academy of Pediatrics spokesperson, "Healthy full-term infants don't need to wear a cap once they get home."

Cold Weather

If it is fall or winter, however, babies do need to continue to wear hats outside. Babies can not regulate their body temperature until about 6 months of age.

Hot Weather

Sun hats can be a help in the summer months or hot climates. They help to keep the sun off infant's heads, which are susceptible to sunburn because they do not have much hair.
