Infant development encompasses the physical, cognitive, and emotional changes that occur as a baby grows. A significant milestone in this journey is the 4-month mark, characterized by rapid progress and new abilities.
At 4 months, babies exhibit remarkable physical development. They gain better control over their head and neck muscles, enabling them to hold their heads steadily and turn them from side to side. They also develop increased strength in their arms and legs, allowing them to push up on their forearms and kick their legs vigorously.
