Question
How long does it take for a newborn’s neck to become stiff?
Answer
A newborn’s cervical vertebrae are not fully developed. It’s best to let the baby sleep lying down most of the time, except when holding them upright to feed. Generally, it’s not until around three months old that a baby can be held upright more stably, and their neck will also become more flexible. If you notice any abnormal symptoms in your child, such as red spots on the skin or vomiting, it is important to take them to the doctor for treatment promptly and avoid self-medicating. Parents should closely monitor their child’s changes and help them receive timely treatment for diseases.
