Baby's development at four and a half months

When a child is growing and developing, we must pay attention to all aspects of the child so that if any abnormal conditions occur, they can be alleviated in time and time will not be wasted. When the baby is four and a half months old, he can eat some complementary foods, which will be of great help to the baby's physical growth in all aspects. So what are the developmental conditions of a baby at four and a half months? Many parents do not understand this.

Development of the baby at four and a half months:

Boys: height 57.9-71.7cm; weight 5.25-10.39kg; head circumference 38.0-45.9cm.

Baby girl: height 56.7-70.0cm; weight 4.93-9.66kg; head circumference 37.2-44.6cm.

The development of a baby's abilities mainly refers to the comprehensive development of gross motor skills, fine motor skills, vision, hearing, touch, smell, taste, language, emotions, and social skills. However, the focus is slightly different for each baby at each age, which is also related to the baby's own developmental characteristics.

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.

After the baby is four and a half months old, when the child is developing, you should pay attention to the reasonable combination of some complementary foods. The baby at four and a half months old cannot eat some greasy food. At the same time, some foods that are not easy to digest should not be given to the baby. The baby should not be given the choice of too hot food, otherwise it will damage the baby's esophagus.
