Question
At what age do infants typically start to lift their heads and roll over? A parent has observed that their two-month-old baby can lift their head but has not yet mastered the rolling skill. Is this within the normal range of development?
Answer
It is normal for a two-month-old infant to be able to lift their head. As for rolling over, infants usually start to learn at around three months old and can master the skill by the latest at five and a half months. Therefore, it is within the normal range for a two-month-old baby not to have learned how to roll over yet. Parents should not be overly concerned. Sometimes, infants suddenly master the rolling skill without realizing it. In daily life, parents can appropriately guide their infants but should avoid excessive intervention, allowing them to develop naturally.
