Common problems in the growth and development of three and a half month old babies

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. What kind of changes will a three-month-old baby undergo? Let us learn about the common growth and development issues of a three-and-a-half-month-old baby through the following article.

Capacity Development

The development of a baby's abilities mainly refers to the overall development of gross motor skills, fine motor skills, vision, hearing, touch, smell, taste, language, emotions, and social skills. However, the focus of each baby at each month is slightly different, which is also related to the baby's own developmental characteristics. The basic skills of a 3-month-old baby include:

Skills that should be mastered (most babies can do this): Able to recognize your face and smell; able to hold the head up steadily; eyes can follow moving objects.

Developing abilities (half of the babies can do it): can scream and make "gurgle" and "coo" sounds; can blow bubbles; can recognize your voice; can do small push-ups.

Advanced abilities (only a few babies can do this): can roll over from prone to supine; when hearing a loud noise, will turn head to look for it; can put hands together and pat toys with hands.

Nutritious diet

Breastfed babies do not need to add other foods if the milk supply is sufficient. However, babies who are mixed-fed or bottle-fed should be fed once every 3-4 hours, 150ml each time, 6 times a day. The total milk intake for the whole day should not exceed 1000ml.

For babies who are mixed-fed or bottle-fed, vegetable juice and freshly squeezed fruit juice should be added in appropriate amounts to replenish the vitamin C lost during milk processing. Generally, feed twice a day, between feedings.

Breast milk is still the best food for babies for three months. It not only provides babies with rich nutrients that are easy to digest and absorb, but also helps babies resist the attacks of diseases. Nursing points

1. Baby urination

Start training your baby's urination habits 3 months after birth. Parents should carefully observe the baby's urination performance and intervals, and help the baby when they think they need to urinate. When helping the baby urinate, they can send out a signal "Shh, shh?" and adopt a certain posture to connect the signals of time, sound, and posture. After repeated repetitions, a conditioned reflex of urination will be formed.

2. Crying at night

When the baby is 3 months old, he starts to learn to lift his head and can support his upper body with his elbows when lying on his stomach. The cervical spine begins to bend forward and the thoracic spine gradually bends backward. To ensure a comfortable position, you should use a pillow for your baby 3 months after birth. Develop the habit of taking a nap in the morning, noon and afternoon, each time for about 2 hours. You can sleep continuously for more than 5 hours at night. However, some babies always cry and make noise when they sleep at night, making young parents exhausted.

3. Accidental protection

Never leave your baby on the edge of a bed, table, or sofa without supervision. Otherwise the baby will suddenly learn to roll over and fall. This is the most common thing in 3-month-old babies, and parents must avoid it.

What are the common growth and development issues for three and a half month old babies? After reading the above, I believe you already know the answer. A three-month-old baby is still so fragile and needs careful care from his parents. He should also go to the hospital for regular physical examinations to see whether the baby is developing healthily. Parents have a great responsibility to ensure that their babies can grow up healthily and happily. They must take good care of their babies and not be careless.
