How long does it take for a baby's neck to straighten up

Patient's question:

No

Doctor's answer:

At 4 months, the baby should be able to hold their head up steadily. However, since I don't know other conditions, such as muscle tone or whether they have torticollis, your question needs to be taken seriously. Generally speaking, if the baby is still unable to hold their head up steadily at 6 months, the situation is quite serious.
