How should the baby's navel have a bad smell?

While in the womb, the umbilical cord provides oxygen and nutrients needed for the fetus to develop. After birth, the umbilical cord is clamped and cut leaving a stump that will eventually fall off and heal to form the umbilical cord. Normally, the umbilical stump before falling off will have a characteristic smell. However, when a newborn's umbilical cord has a foul odor after it falls off, this can be a problem and the baby needs proper care.

Newborn babies are covered with amniotic fluid, secretions from the birth canal and may not have a pleasant smell right after birth. After bathing (except around the navel), this odor should disappear.
After birth, the umbilical cord that attaches the baby to the mother will be severed. A remaining segment of the cord stump that turns from pink to purple-blue may remain until it is completely shed. At first, the stump of the umbilical cord that has not fallen off may have an unpleasant odor, but this odor will fade after the remaining stump has completely fallen off.
In the past, pediatricians recommended washing the stump of this umbilical cord with alcohol. However, the effect of alcohol will further dry and irritate the very delicate skin of babies. This leads to the risk of skin peeling and secondary infection, so the use of alcohol to clean the baby is no longer recommended. Thus, the remaining umbilical cord is best left to dry and fall off naturally.
Rarely, the remaining stump of the umbilical cord can become infected and may present with redness, swelling, and itching on and around the umbilicus, with or without the umbilicus, with yellow pus, green. If infected, the umbilical cord of the newborn baby has a very unpleasant odor and the baby will also react by feeling pain to the touch.
In addition, the baby can also have a high fever due to the infection and become very irritable, refuse to feed and even sleep for a long time. In this case, the baby will need appropriate umbilical wound care and even systemic antibiotics if the infection is severe.
Because about 10-20% of babies have an umbilical hernia at birth, because the abdominal muscles cannot fully close after birth, part of the intestines or the contents of the abdomen may bulge through the opening and be lost. infection. This is the result that causes the baby's navel to have a bad smell. An umbilical hernia is easy to diagnose by seeing a small tender bump around the belly button, and this usually subsides by the time the child is three to four years old.
On the contrary, if the child still eats and sleeps well, does not fuss, then there is nothing to worry about. Parents should leave the rest of the umbilical cord as it is and the smell of the baby's belly button will gradually subside after a few days and disappear naturally. However, do not attempt to resolve a baby's umbilical cord odor by forced removal. That will be painful for the child as well as possibly causing infection and potentially scarring on the abdominal wall that is unsightly.

After the baby is born, the midwife or obstetrician will clamp and then cut the umbilical cord. After the cut is complete, a small piece of the umbilical cord will still be attached to your baby's navel - this will be about 2-3 cm long and is called the umbilical cord.
Over the next 7 to 14 days, the base of the umbilicus will darken, wither, shrivel and eventually fall off. The remaining small wound will heal and become the navel on your baby's abdominal wall. Here are some easy care tips for your baby's umbilical cord stump before it falls off.
