Is It Harmful for a Baby to Arch Their Back?

Question

My baby is four months and fourteen days old. Today, when I held the baby with one hand, the baby suddenly arched their back halfway. Is this action harmful to the baby?

Answer

Generally speaking, a four-month-old baby’s body is still very soft, and such a small movement usually does not cause too much harm to the baby. As long as the baby does not show any unusual symptoms, there is no need to worry excessively. However, for safety reasons, it is recommended to use both hands when holding the baby and to pay attention to supporting the baby’s head to avoid unnecessary risks.
