Your 9 month old is on the move! He is probably crawling, pulling himself up on furniture, cruising, or maybe even taking his first few steps.
Baby is becoming even more aware of his environment now and wants to explore everything in it. He will fling toys to the floor, examine an insect in the grass, and bang objects together just to see what happens. Babble seems to have increased too!
Read on to find out what else is to unfold as your little one hits the 9 month old milestones.
What You Should Know
- Take baby to his 9 month old checkup. The exam might involve a blood test to check the baby for signs of anemia.
- You can now start cleaning your little one’s teeth with a soft baby toothbrush or cloth and warm water.
- Encourage the baby to explore but learn to say “No!”
- Hold baby’s hands and help him move around on two feet. It will encourage him to walk.
The Most Adorable 9 Month Old Milestones
By the time your baby turns 9 months old, he will be displaying all kinds of traits from happiness, to fussiness, to curiosity. At this age, the baby is exploring and familiarizing himself with the world around him, so be patient and give your little one sufficient opportunity to learn. Baby proof your furniture and living room (if you haven’t already) and set up a safe place with some toys for baby to explore.
Below are some of the changes you should note in your 9 month old baby development chart.
Weight And Length
According to the World Health Organization (WHO), a 9 month old should weigh about 19.5 pounds for boys and 18.2 pounds for girls. The average height (length) should be around 28.2 inches for boys and 27.5 inches for girls.
Of course, your baby’s weight and length can be higher or lower than what’s suggested by the WHO and baby still be healthy. Every baby grows differently; the most important thing is making sure that yours is showing a steady curve every month. If you have been following your baby checkups religiously and the pediatrician hasn’t pointed out any problems, then your little one is growing at a healthy rate.
This month, your baby still rocks the typical ‘baby’ look – large head, chubby limbs, and a cute potbelly. But this also happens to be one of the months when the baby is the most active, which means the baby will lose most of this chubbiness and gain more lean muscle.
The Five Senses
Baby’s vision has been improving day by day. He can now see clearly across the room. He can also read and copy gestures: he will clap if you clap, try to make a face if you pull one, or try to throw toys across the room if you do.
Also, the muscles that control your baby’s eye movement are much stronger now, allowing him to follow moving objects. He will track a falling balloon or a moving toy, and he may even point at an item you accidentally dropped.
Your little one also understands that adding pointing to looking has more weight than just looking and doing nothing, when interested in something. He will use his index finger to show you something he wants rather than just looking at it and crying.
Your 9 month old learns by listening. He will not only listen to what you say but will also try to repeat it. Baby understands what “No!” means now. You may see him avoid doing something that provokes a negative instruction from you.
Baby at the ninth month is not only touching objects but also hitting them against each other, passing them from one hand to the other, or throwing them at short distances. His pincer grasp is quite developed from last month’s too, meaning he can pick small objects pretty well. Make sure you are inspecting baby’s play mats and play yards frequently for choking hazards.
Advancement in communication is perhaps one of the most notable developments in your 9 month old milestones. Baby at this age will be babbling and jabbering away nonstop and those babbles may start sounding like real sentences.
“So exactly what words should my 9 month old be saying” you may ask? Though no one can understand the baby’s language but himself, sometimes your 9 month old will say real words like “mama” and “dada” that even you can understand. He might even use them to describe you!
What Is A 9 Month Old Supposed To Be Doing?
Baby at 9 months should be doing the following:
- Rolling from front to back and vice versa
- Creeping or crawling on the ground
- Pulling himself up to a standing position using furniture
- Sitting in an upright position (and unsupported) on a high chair
- Cruising furniture by walking
- Standing up without support
- Going for or pointing objects that he is interested in
- Taking a few steps or even walking
- Picking finger foods and putting them into his mouth, all thanks to the newly developed grip; pincer grasp
- Waving “hi” or “bye”
What Skills Should A 9 Month Old Have?
A 9 month old should have the following skills:
- Object permanence: Baby will remember his favorite toy and look for it.
- Parachute reflex: Your 9 month old puts his hands forward whenever his head faces down. This is the body’s reflex to prevent a baby’s head from injury in case he falls.
- Clingy toward parents and nervous around new faces: Baby prefers being close to you and may cry if someone takes him away from you. He will also panic and cry when around strangers.
9 Month Old Food
Proper feeding is key to the growth and development of infants, and parents with 9 month olds would probably like to know:
What Should A 9 Month Old Be Eating?
A 9 month old should be eating solid baby foods supplemented with breast milk and/or formula. Baby needs at least 750 calories a day and half of that should come from formula or breast milk.
As baby hits 9 month old milestones and transitions into a ‘bigger’ baby, the order at which you offer food and breast milk might change too. When the baby started solids, you may have offered formula or breast milk first and then food but at this age, you can feed him solids first and then nurse later.
How Many Solids Should My 9 Month Old Be Eating?
A 9 month old baby should be eating about 3 meals a day. You can add a snack or two between meals, but the baby will do just fine with 3 meals considering you are feeding him breast milk or formula too.
9 Month Old Sleep
Most babies at 9 months will sleep through the night. On average, your little one at this age will sleep about 14 hours per day; 11 hours at nighttime and the remainder during the day, split into 2 naps.
However, sometimes sleep may be interrupted by growth spurts, teething, or illnesses. Don’t worry if your baby is experiencing temporary sleep disturbances. Just continue following your bedtime routine by putting him to bed a little drowsy and letting him soothe himself to sleep. This is also the appropriate age to move your little one into his bedroom or a full-sized baby crib if you haven’t already.
A Day In A 9 Month Old Life
9 month olds love to play, so be prepared to offer lots of interactions and activities that boost your child’s growth and education. But many first-time parents may wonder, “How can I help my 9 month old development?” Here is an idea:
- Let baby play: This is the most effective way to exercise his muscles so he can develop at a steady rate and mark the 9 month old milestones at the right time.
- Have meaningful conversations with your baby: Name different objects around the house together. Show him gestures (like “Hi” and “Bye-Bye”) and say their meanings. You will hear him try to babble the words after you.
- Read brightly-colored books: Babies at 9 months love looking at bright objects. Read colored picture books regularly together to help stimulate baby’s vision.
- Train baby to feed himself: Let your child pick finger foods from his plate and feed himself. This will help him enhance the pincer grasp.
- Introduce family members: Let baby spend a day or two with the entire family. Familiarize him with every member and their relationship to the baby (like “that’s sissie” “this is grandma”). It will make it easier for him to remember them as he grows older.
When Should You Be Concerned?
If your little one is not doing everything displayed in a 9 month old baby development chart, there should be no reason to worry. He could just be a little delayed, so be patient. However, if the baby shows any of the following symptoms, it would be wise to talk to a pediatrician:
- Isn’t feeding properly
- Doesn’t respond to his name
- Hasn’t put on any weight for the past three months
- Doesn’t say simple words like “mama” and “dada”
- Doesn’t show any reaction when you leave him alone in the room or with strangers
- Doesn’t move at all
- Doesn’t reach for nearby objects
- Doesn’t recognize you
Is Your 9 Month Old Healthy?
Baby has another checkup with the pediatrician this month. He will have his head circumference, his weight and his height measured and checked against the standard 9 month old baby development chart. If you have specific questions or concerns about your little one’s health, this is the time to talk to your pediatrician. For instance, you may want to know:
“How many teeth should a 9 month old have?”
At 9 months old, most babies will have around 4 teeth; the bottom central incisors (lower front teeth) and the top central incisors (upper front teeth). But it is also normal for the top lateral incisors and lower lateral incisors to erupt at around this time.
You may also want to know, “What is a high fever for a 9 month old?”
Most doctors will consider a rectal temperature of 38˚C (100.4˚F) a high fever for 9 month olds. The normal temperature of infants at this age should range between 36˚C (97˚F) and 37˚C (100.3˚F).
My Babies Planet Overview
The ninth month is a great time to watch your baby play and develop in many exciting ways. Your little one is slowly learning to be independent physically, emotionally, and cognitively. Don’t push him into achieving the above milestones. Instead, provide a supportive and stable environment and let the baby reach the developmental stages at his own pace.
