When a baby bends his head to one side is that abnormal?

When a baby bends their head to one side, it can be a normal developmental behavior as they explore their surroundings and strengthen their neck muscles. However, if the tilting persists or is accompanied by other concerning signs, such as limited neck mobility or developmental delays, it may indicate a condition like torticollis. It's always best to consult a pediatrician if there are any concerns about a baby's posture or development.
