How does a three-month-old baby develop?

For babies, due to physical reasons, newborns may not be able to feel the world. However, when the baby is three months old, he can basically see some things around him and perceive some things. So, do you want to know how a three-month-old baby develops? Next, let me explain it to you.

At 3 months old, the baby's posterior fontanelle has almost closed, indicating that the cartilage has hardened into bone. Your baby will sleep longer stretches at night and have regular naps during the day. The baby's primitive reflex behaviors begin to disappear and are replaced by spontaneous movements. The baby's vision has also developed to the point where he can see everything within 1 meter.

Growth indicators

The weight of a boy is 4.69-9.37kg and the height is 55.3-69.0cm; the weight of a girl is 4.40-8.71kg and the height is 54.2-67.5cm.

Capability Indicators

When your baby is lying on his or her stomach, he or she not only lifts his or her head, but also lifts it very high.

Physical appearance and growth: This period is when the baby's physical development is the fastest, with weight increasing by about 1 kg per month and height increasing by about 4 cm per month; head circumference will increase by about 1.25 cm. At 2 months, the fontanelles on the baby's head are still open and flat, and the baby looks a little chubby, but as he uses his hands and feet more actively, muscles begin to develop and the fat will disappear. When the baby is three months old, its height has increased by about 1/4 compared to when it was born, and its weight has increased by 1 times compared to when it was born. The weight of a baby boy is 4.1 to 7.7 kg and the height is 55.8 to 66.4 cm; the weight of a baby girl is 3.9 to 7.0 kg and the height is 54.6 to 64.5 cm.

Movement: During this month, the Moro reflex and stepping reflex will gradually disappear. Most of the reflexes your child has ever had will peak and begin to disappear at 2 to 3 months; after the reflexes disappear, he may be temporarily inactive, but his movements will become more detailed and purposeful, and will develop steadily towards maturity. By the end of the month, he could even kick himself from the front to the back with his legs. He will look at his own hands carefully, clasp his hands together and play with them in front of his chest. But at this time his hand-eye coordination was uncoordinated, he seemed clumsy, and often could not reach the toys. The development of hand movements is also called the development of fine motor skills. Around this time, as the grasping reflex disappears, children begin to grasp unconsciously, which marks the beginning of the development of hand movements.

The above is what I want to introduce to you today about the development of three-month-old babies. Parents can learn about it. I hope my sharing will be helpful to everyone. The editor reminds all mothers that the baby’s physical fitness is relatively poor, so you should pay more attention to the baby’s physical condition. The editor also wishes your baby good health.
