In contrast to a three-month-old baby, a four-month-old baby is usually strong enough to hold up its head independently.
A baby typically achieves an important developmental milestone around four months of age: developing enough neck and upper body strength to support their head on their own. This achievement reflects improved motor abilities and control over the neck muscles. When a baby can hold their head up on their own, it makes it easier for them to explore their surroundings and develop their cognitive and sensory abilities.
By offering supervised tummy time and moderate neck exercises, parents and other caregivers can support this developmental milestone. Your baby will eventually gain more control over his head movements as his neck muscles continue to strengthen, paving the way for additional physical and cognitive development.
