Introduction
A baby's body temperature usually rises during breastfeeding, possibly due to increased heat production from the physical effort involved, or reduced heat dissipation. Infants exert significant effort while nursing, generating more body heat. If breast milk supply is insufficient, the baby may need to suck harder and for a longer duration, which can lead to a mild increase in body temperature. Typically, the temperature returns to normal after about 15 minutes of rest.

Babies usually experience a slight increase in body temperature while drinking milk, which may be due to increased heat production from the physical effort of feeding, or reduced heat dissipation.

Infants generate more body heat because they exert significant effort during breastfeeding. Especially during breastfeeding, if there is insufficient milk supply, babies tend to suck harder and for longer periods, which can lead to a mild rise in body temperature. Therefore, attention should be paid to the baby's feeding habits. Generally, the body temperature returns to normal about 15 minutes after feeding and resting. When a baby is held tightly during feeding, heat dissipation is reduced. Wearing too many or tight clothes further limits heat loss, potentially causing symptoms such as sweating on the head, flushed face, and fussiness. Dietary adjustments should be considered—allowing the baby to rest briefly before feeding, for example. Additionally, it's important to open up blankets to facilitate cooling and help remove clothing, especially around the neck, to promote better heat dissipation.

When feeding babies, sterilize bottles beforehand. For breastfeeding infants, ensure the breasts are kept clean. After each feeding, gently wipe the area with a clean towel or wipe.
