The growth law of 9-month-old baby is similar to that of last month. 9-month-old baby development indicators mainly include the following points:
Physical standard: weight: at the age of eight months, the baby boy weighs 6.9 ~10.8kg; The baby girl weighs 6.3 ~10.1kg.
Length: the length of the baby boy is 65.7 ~ 76.3 cm; The baby girl is 63.7 ~ 74.5cm in length.
Teeth: grow 2-4 deciduous teeth. Development Law: Weight: The baby's weight is expected to increase by 0.22 ~ 0.37kg this month.
Height: The baby's height can be increased by1.0 ~1.5cm this month.
Head circumference: the head circumference increased by 0.67 cm.
The 9-month-old baby has also made progress in action, mainly in:
Sit and lie freely: you don't need to lean on anything, you can sit stably for a long time. When sitting, you will lie down or lie down by yourself instead of passively falling down.
Began to climb forward: but the movement of limbs is not coordinated, and the stomach begins to leave the bed surface, but sometimes it still crawls forward with its stomach.
Support can stand up: the railing on the bedside can stand up, but it will not step forward by itself. At the end of nine months, some babies can stand alone for a few seconds without holding things.
9-month-old baby's language development
After 9 months, the baby's language development has made great progress, and the parents are no longer communicating unilaterally, because the baby can understand more languages now!
Before the baby can't say many words or any words, he may understand more words than you think. Therefore, parents should talk to their children as much as possible, which can increase their understanding ability, tell them what is happening around them, and make your language simple and special.
Whether you read it to him or talk to him, give your child enough time to participate. Ask questions and wait for the child's response, or let the child guide himself, which will help the child's thinking and language development.
At this time, he may have been able to answer questions in simple language; Can do 3 ~ 4 kinds of actions to express language; I have different reactions to different sounds. When I hear a "no" or "motionless" sound, I can temporarily stop my activities, know my name, stop my activities when I hear my mother say my name, and continue to imitate my voice. When you hear a familiar voice, you can hum along, say a word and express your actions, such as waving your hand when you say "no" and pointing to something when you say "this, that".
The above is the reference standard of 9-month-old baby's language development. Mawang reminds you that if your baby doesn't reach this standard, you don't have to worry too much, because the language development standard varies from person to person, so you can observe it for a while.
