Question

My baby is four and a half months old. Just now, when my older sister cried, she watched her and then cried loudly herself. I’m not sure what’s going on. Besides, she has the habit of curling her thumb inward. When she reaches for things, she opens her hand, can hold onto things, but drops them after a while. Is this normal?

Answer

Based on the current description, these symptoms appear to be part of the normal developmental process. It is common for babies at this age to start imitating actions and sounds, which is part of their learning and exploration of the world. The habit of thumb curling is also a common phenomenon in infants and usually improves with the development of hand skills. However, if you have any concerns about your baby’s development, it is recommended that you consult a professional doctor at a regular hospital when you are worried. Remember not to give your baby any medication at home unless instructed by a doctor. The above suggestions apply to the question “My baby is four and a half months old and just now my older sister cried.” I hope this helps you, and wish you and your baby health!
