    How much do you know about your baby and newborns in general? Today, we switch on the "Newborns 101" mode and answer your most pressing questions about baby feelings, sleep, and many more.

    Are babies born pink, clean, and smooth?

    The appearance of a newborn may be startling.

    The baby’s cyanotic little body covered with a cheese-like substance, wrinkled skin, strangely shaped head, nose curled to the side or flattened, and folded ears — all that is the result of the baby staying in the womb for a long time and having a difficult journey through the birth canal.

    Newborns recover quickly, though.

    The cartilages straighten out, the head rounds out, and the skin becomes pink and velvety with elastic wrinkles.

    Is it true that newborns should be taught to distinguish between day and night?

    Babies are born with undefined sleep-wake patterns. 

    They need help to understand the time of day. In the daytime, there should be as much sunlight in the house as possible.

    When the baby is active, play with him/her. Don’t try to mute the usual noises during the baby’s daytime nap.

    Observe the bathing-feeding-sleeping ritual. At night, quietly change diapers and avoid bright lighting.

    Babies usually adjust to the family schedule within 6–8 weeks.

    Is baby vaccination dangerous?

    In the first few days of life, newborns are subject to vaccination against diseases that pose a threat to their lives and health.

    Some parents worry that the baby is too young to be vaccinated, but these fears are unfounded.

    A newborn’s immune system is still immature, but it’s ready to develop an immune response to vaccine administration.

    The resulting antibodies will protect the baby from serious infections in the future.

    Are white spots on a newborn’s face a sign of a disease?

    Milia look like small pimples with single or multiple whiteheads inside.

    They can be found on the face and sometimes on the gums in 40–50% of newborns.

    This is the result of sebaceous gland obstruction and is not considered a disease.

    Don’t try to squeeze or clear up the milia as this may leave scars.

    The milia will disappear in a few days or weeks when sebaceous gland function is normalized.

    Do baby hiccups mean they are freezing?

    Hiccups are convulsive contractions of the diaphragm with the glottis closed.

    They occur if a baby has overeaten, swallowed a lot of air, or drunk something cold.

    Hiccups can also be caused by general hypothermia.

    Hiccup fits usually last for 10–15 minutes and go away on their own.

    They don’t trouble the baby, but you can latch the baby onto your breast or give the baby a pacifier to help regurgitate air.

    If the hiccups happen too often, or last for a long time and exhaust the baby, or are accompanied by coughing or regurgitation, please consult a doctor.

    Will shaving a baby’s first hair make it grow thicker?

    A baby's hair is determined genetically.

    Shaving the baby’s head will not make the hair grow thicker because cutting the hair doesn’t affect the hair follicles located in the dermis.

    A temporary effect is achieved because the hair becomes the same length right after the haircut.

    Can diapers cause infertility in boys?

    Diapers contribute to scrotal temperature increase by 1,8 °F (1 °C).

    Scientists suggest that this can affect sperm production when entering the reproductive age.

    This is confirmed by a decline in male fertility due to low sperm count observed in recent decades.

    However, no direct connection between infertility and wearing diapers in early childhood has been found yet.

    Do babies sleep very deeply?

    When falling asleep, a baby enters the rapid eye movement stage, or light sleep, and can sob, smile, tremble, or wake up from any careless noises.

    Within 10–20 minutes, the baby enters the deep sleep stage, when they are particularly difficult to wake up.

    The baby’s breathing slows down, and the muscles relax.

    The sleep stages alternate, taking approximately equal amounts of time.
