What are the intellectual development standards for a 9-month-old baby?

The motor skills of a 9-month-old baby have become very strong. They usually look very active and are always moving around on the ground during the day. At this time, they no longer need passive gymnastics training from their mothers. But how is the intellectual development of a 9-month-old baby? If you are not very clear, the editor below will explain it to you in detail.

Physical appearance and growth

The baby's growth pattern this month is similar to last month.

Physical standards: Weight: When a baby is eight months old, the weight of a boy is 6.9 to 10.8 kg; the weight of a girl is 6.3 to 10.1 kg.

Height: The height of a baby boy is 65.7 to 76.3 cm; the height of a baby girl is 63.7 to 74.5 cm.

Teeth: 2-4 deciduous teeth emerge. Development pattern: Weight: Your baby is expected to gain 0.22 to 0.37 kg in weight this month.

Height: This month the baby's height can increase by 1.0 to 1.5 cm.

Head circumference: Head circumference increased by 0.67 cm.

sports

Sit or lie down freely: No need to lean on anything, able to sit steadily for a long time. When sitting, the child will lower himself or herself to a prone or lying position instead of falling passively.

Start to crawl forward: but the limbs are not yet coordinated, the belly starts to leave the bed, but sometimes it still crawls on its belly.

Can stand up with support: Can stand up by holding the railing at the head of the bed, but cannot take a step forward on his own. By the time they are almost nine months old, some babies can stand alone for a few seconds without support.

intelligence

A 9-month-old baby's intellectual development may not be very good. At this time, he cannot speak clearly, but he can make up some simple things. If the baby has some intellectual problems, you must take the baby to the hospital for examination. If the baby's intelligence is not good as soon as possible, some training can be used to improve the baby's condition.

Baby problems are always what parents worry about most, so parents must pay more attention to the baby's care in normal times. The baby may be more frantic at this stage and may grab things randomly, so the editor reminds you to pay more attention to the baby's eye care at this stage to prevent the baby from putting unclean things in the eyes.
