The fourth month is a critical point in the growth of babies

A four-month-old baby has almost begun to develop all aspects of his abilities. The baby's vision, hearing, touch, taste and movement aspects begin to develop gradually. At this time, all expectant mothers and fathers should guide their babies and slowly teach them some simple words and actions from life, so that they can recognize and feel the world as soon as possible.

A 4-month-old baby's head circumference and chest circumference are roughly equal. The baby is more than 10 cm taller than when he was born, and weighs about twice as much as when he was just born. When lying prone, the baby's upper body can be fully lifted; the legs can be raised to kick off clothes and quilts; the vision becomes very flexible; the baby begins to babble and responds to adults' teasing with voice; and complementary foods can be added. The basic abilities of a 4-month-old baby include:

Skills that should be mastered (most babies can do it): smile and laugh out loud; be able to support body weight with legs; be able to make "coo" responses when you talk to him.

Developing abilities (half of babies can do this): Can grab a toy; can roll over from prone to supine.

Advanced abilities (only a few babies can do this): can imitate dad's "da da" sound; grow the first tooth; may be ready to start adding complementary foods. Add rice porridge, juice and vegetable soup appropriately. After the child has adapted to rice porridge, juice and vegetable soup, start adding protein foods. At the beginning, only 1/4 egg yolk paste can be added, and egg whites must not be fed.

Rice porridge: Rice porridge is less likely to cause allergies in babies.

Protein foods: Egg yolks can be made into a paste, or some chicken liver can be added to increase iron.

Fruit juice: vegetable juice, orange juice, apple juice, tomato juice.

For babies who are mixed-fed, since formula milk is added, the ratio of water to milk powder is fixed, so the baby needs to be fed boiled water separately. When choosing formula milk, you should also carefully select formula milk with added β-vegetable oil (affinity structural fat) and moderately hydrolyzed protein. This type of milk is easier for babies to absorb, does not cause irritation or constipation, and is more baby-friendly.

The four-month-old period is very critical for babies, as it affects the key moments of their growth and development. Therefore, all expectant fathers and mothers should attach great importance to this period of time. Do a good job in guiding your baby's healthy growth and development, prepare nutritious diets for your baby, develop reasonable and healthy exercises for your baby, and guide your baby with words.
