After 9 months of growth, the baby has gradually become lively and can climb and stand freely, and his mobility has been greatly enhanced.
At this time, the baby's development has also begun to mature. Now I will introduce to all mothers what are the indicators of baby development at 9 months.

Head circumference: Head circumference increased by 0.67 cm.
The nine-month-old baby has also made progress in its movements, mainly in the following aspects: sitting and lying freely: it does not need to lean on anything and can sit steadily for a long time.
When sitting, you will lie down or lie down on your own instead of passively falling down.
I started to climb forward, but the movements of my limbs were not coordinated. My stomach began to leave the bed, but sometimes I still used my stomach to crawl forward.
You can stand up by holding something: You can stand up by holding the railing at the head of the bed, but you can't step forward by yourself.
As they approach nine months old, some babies can stand alone for a few seconds away from objects in their hands.
The nine-month-old baby's language development has made great progress, and the nine-month-old baby's language development is no longer having unilateral communication, because the baby can now understand more languages! Before your baby cannot say many words or any words, he may understand more words than you think.
Therefore, Dear Parents, talk to your child as much as possible to increase your child's understanding ability and tell him what is happening around you. Make your language simple and special.
No matter whether you read to him or talk with him, give the child enough time for participation.
Ask questions and wait for the child's reaction, or let the child guide him himself. This will help the child develop his thinking and language.
By this time he may be able to answer questions in simple language.
Can do 3 - 4 actions that express language.
Have different reactions to different sounds. When you hear the sound of "no" or "no movement", you can temporarily stop your activities and know your name. When you hear your mother say your name, you can stop your activities, and you can continuously imitate your voice.
When you hear a familiar voice, you can hum along, say a word and express it with an action, such as waving your hand when saying "no" and pointing your finger when saying "this, that".
The above are the reference standards for language development for a 9-month-old baby. Ma.com reminds you that if your baby does not meet this standard, you don't have to worry too much, because the language development standards vary from person to person, so you can observe it for another period of time.
At 9 months of age, infants' visual development is advanced. At this age, babies are able to recognize what they see and can fully reflect it back.
Not only can they recognize their parents' appearance, but also their physical characteristics and the clothes they wear. Therefore, they are likely to cling to their mothers or fathers and cry when approached by strangers.
At 9 months, babies selectively look at things they enjoy. For example, they may watch cars running on the road, play with children, or observe small animals as they can see smaller objects.
Infants are very fond of moving objects or objects in motion, such as the second hand of a clock, pendulums, escalator that is rolling, rotating small decorations, flying butterflies, moving insects and so on. They also like to watch rapidly changing TV advertisements. Have you found your baby loves watching TV advertisements? Don't worry, this is the visual system of your baby developing.
9-month-old babies are starting to recognize colors, and their mother continues to teach them: "This is a red balloon, this is a yellow balloon, this is a green balloon."
Although babies do not understand the change of color and cannot distinguish it, they can remember colors. If different colored balloons are placed in different places, when asked "What's that red balloon?" baby will turn their head to look at the red balloon.
The yellow balloon? The baby turns its head to look at the yellow balloon.
Regularly, moms can engage their babies in such cognitive games to enhance and stimulate the development of the baby's visual system.
I've begun to have a preliminary understanding of gender.
If he always holds the baby, the baby likes to be held by a man who is about the same age as his father.
Baby who is held by their mother more often prefers to be carried by a woman whose age is similar to their own.
9-month-old babies are growing healthily, and while parents are busy nurturing their growth, it's important to pay attention to common illnesses in young children.
At Mamanet, we will introduce some common diseases in infants aged 9 months.
1. Chickenpox: If a baby contracts chickenpox, it is advisable to cover them with cotton gloves to prevent them from rubbing their eyes. This can prevent the virus from affecting the eyes and cause keratitis, leaving scars on the cornea that can affect vision.
To prevent chickenpox, it's best to have your child vaccinated against the virus. Additionally, avoid crowded places.
2. Measles: Measles primarily affects the skin and respiratory tract, presenting as a highly contagious disease.
The incubation period for this disease is 7-14 days. The risk of complications associated with measles in children is high, including the possibility of pneumonia.
If a child has measles, you need to pay attention to the cleanliness of his skin, eyes, mouth and nasal cavity. If the condition is not serious, you can carry out isolation treatment at home.
If the condition is serious, you need to be sent to hospital for treatment.
3. Learn to walk: Babies start to learn to walk, usually between December and 14 months, but some children develop early and may advance to 9 months.
But you must note that letting your baby crawl before 9 months is more beneficial to your baby than starting to walk, because the baby's cerebral nervous system is not yet well developed, and walking requires guidance and coordination from the cerebral nerves.
4. Baby diaper rash: Diaper rash is a long-standing problem that plagues many parents. Once you are lazy and fail to change your child's diaper in time, diaper rash will come to trouble your baby.
Almost 50% of babies have experienced red buttocks, so prevention is especially important.
Pediatric experts have recommended the three steps of "wet wipes-hip protection cream-talcum powder" to protect the buttocks without worrying.
You may wish to follow these three steps when caring for your baby's buttocks every day.
First, use a pH-weak acid milk wipe to clean oily dirt from the skin. Second, apply an oxyzolide-based diaper rash cream to isolate urine irritation and bacterial infections. Finally, apply talcum powder to absorb moisture and smooth baby's skin.
