A three-month-old baby has entered a new stage of growth, officially stepping into the infant stage. Compared to when they were born, their changes are significant, reflected in various aspects including physical appearance, physical development, and skill acquisition.
In appearance, the babies’ skin has become more delicate, glossy, and elastic; their faces are gradually cleaner, with a reduction in milk crust and relief from eczema. From the perspective of physical growth, the average weight for boys and girls is approximately 6.4 kilograms and 5.8 kilograms, respectively, while their lengths are around 61.4 centimeters and 59.8 centimeters. These figures illustrate their rapid growth over just three months. Head circumference, an important indicator of brain development, averages 40.8 centimeters for boys and 39.8 centimeters for girls, which holds significant implications for the babies’ future intellectual development.
The growth in weight and height is particularly notable this month. Generally speaking, babies may gain between 0.9 and 1.25 kilograms, while their height can increase by about 3.5 centimeters, allowing their little bodies to grow robustly almost every day. The head circumference will also expand by approximately 1.9 centimeters, and although there is no apparent change in the anterior fontanel, it still requires careful protection to avoid injury.
In terms of skill development, as the innate grasp reflex gradually diminishes, babies begin to attempt to grasp objects unconsciously, marking the initial development of hand movements. They will strive to reach for nearby objects, even though their movements may still be somewhat clumsy. Once they obtain a toy, babies will hold it tightly and instinctively try to bring it to their mouths to explore through sucking. Additionally, observing and playing with their little hands has become a significant enjoyment for them, and they may even start learning to suck their thumbs, which is a normal exploratory behavior during their growth process that parents need not overly intervene in.
A three-month-old baby is in a crucial period of rapid change and skill exploration, with each day filled with new discoveries and surprises of growth.
