Changes in behavior in newborns

Unusual behavior changes in newborns (0-3 months)

Parents get to know their baby very quickly and are usually the first to notice when something is off. Any sudden and persistent change in a newborn's usual behavior is a reason to look at them more closely. It can be the first—and sometimes the only—signal of the onset of illness or another discomfort.

Which changes should you pay attention to?

• Change in activity: Sudden lethargy, sleepiness that is hard to interrupt for feeding, is a very concerning sign. Likewise, sudden, unusual irritability and inconsolable crying.
• Changes in feeding: Sharp refusal of the breast or bottle, weak sucking.
• Change in the character of crying: Appearance of a piercing, monotone, or, conversely, weak, whimpering cry.
• Unusual movements: Appearance of stereotyped, repetitive movements that were not present before.

What could this mean?

Sudden changes in behavior are almost always a sign that the baby is feeling unwell. It can be the first symptom of an infectious disease (even before the appearance of fever), pain, neurological problems, or other discomfort. Trust your parental intuition. If your child's behavior worries you, it is better to consult a pediatrician.
