Growth and Developmental Characteristics of 9-month-old Babies: Part 1

Infant Belta Folic Acid

In the first nine months of life, an increasing number of children begin to crawl and stand while holding onto something. In many cases, the remarkable development of motor functions coincides with the onset of following. Although this is part of the baby’s growth process, many mothers and fathers may be troubled by the situation where the baby’s range of activities has expanded to the point where they cannot leave the house even for a moment.

Here, we will explain the growth of a 9-month-old baby.

Growth of a 9-month-old Baby

Nine months of age, just before their first birthday, is the time when they begin final preparations for walking on their own and learning to speak. The development of motor skills, which began with holding up the head and continued with turning over, crawling, and sitting continues at an accelerated pace. Emotional growth is also significant.

Let’s take a look at what exactly a 9-month-old baby can do: 


Usually, it says that approximately 90% of children are able to crawl and move around between the ages of 9 and 10 months.

The development of muscles and nerves throughout the body, including the legs, hips, back, and arms, enables crawling, and repeating this process further improves motor function. Repeating this process will further improve motor function, leading to standing on one’s hands and walking alone.

To promote further motor development, provide a large space for your baby to move around freely once he or she is able to crawl.

Then, when he or she gets used to crawling a little, let them practice “going up and down” by making steps or mountains out of bedding or cushions to help them develop a sense of physical balance.

Encourage your child to crawl in a varied manner, incorporating a variety of play activities so that more muscles and nerves can be exercised.

Beginning to stand while holding onto something

About 80% of children master standing on their own while holding onto something between the ages of 9 and 10 months.

Standing while holding onto something is a motor development that strengthens the legs and feet and is the first step to begin walking on one’s own. It also has the effect of stimulating curiosity and promoting emotional development, since the child’s line of sight changes dramatically when he or she is able to stand while holding onto something.

When they first start to stand while holding onto something, they may appear to be wobbly on their toes, but as they get used to it, they will be able to stand firmly on their feet, walk with their feet on the ground, and play by themselves while standing.

Parents will be deeply moved by this remarkable growth from the newborn stage, when they are confined to bed.

Babbling begins

At the age of 9 months, the number of children who say “mama,” “papa,” “mamma,” and so on gradually increases. Even if they don’t produce clear words, they begin to babble actively, making a combination of multiple sounds such as “baa baa,” “boo boo,” and so on.

It is said that approximately 10% of children produce meaningful words between the ages of 9 and 10 months. This percentage is lower than in 2000, and overall language development is slower than before.

Although there are large individual differences in the speed at which babies acquire words, they learn by hearing a variety of words.

In today’s nuclear family, it is not unusual for mothers and babies to be alone during the day, and babies have fewer opportunities to listen to conversations. In order to promote language development, it is important to talk to your baby and respond to him or her when he or she is in a good mood and babbles a lot.


Around this stage, you will see many growths of your baby dramatically. You may be surprised by them every day. They start moving around, so keep your eyes on them always.
