Ages 8 to 12 Months—5 Months of Magical Milestones

What can you expect as your baby approaches year 1?

Every baby moving toward toddlerhood develops at a slightly different pace. What babies between the ages of 8 months and 1 year share are developmental mile markers that each will reach, sooner or later. Hold on tight, parents, and enjoy the ride!

Feeding schedule at ages 8 to 9 months: At 8 to 9 months of age, your baby may be drinking 7 to 8 fl oz of formula or breast milk, 3 to 4 times a day.

Feeding schedule at ages 9 to 12 months: Between 9 and 12 months, your baby will likely be drinking 7 to 8 fl oz of formula or breast milk, 3 times a day.

Your baby’s world at 8 months

Generally, at 8 months, your little one is starting to crawl, cruise, and experiment with all-new ways to explore the world around them. 

They’re on a roll. By the end of this month, they will likely be able to: 

Crawl 
Inspect toys 
Say “dada” without necessarily knowing what it means 
Move from lying on their stomach to a sitting position

Fine-tuning fine motor skills. Support your baby’s fine motor skills by: 

Helping them stand when they are near a table or sturdy object and use it for balance. Encourage them to “cruise” along the furniture by holding a favorite toy just out of reach. 
Encouraging them to bounce while supporting them in a standing position. 
Placing a toy out of reach and encouraging them to crawl toward it.

Safety tip: Make sure baby’s crib mattress is in the lowest setting once they can pull up to stand.  

For a good night’s sleep, create a routine. Now is a great time to create regular bedtime rituals. A soothing activity that lasts 10 to 30 minutes, such as reading a picture book or doing quiet activities together, is ideal. This will help your baby look forward to bedtime and find it easier to adjust when you finally leave the room.

Your baby’s world at 9 months: time to shake, rattle, and roll!

At this age, your baby might be developing the ability to grab anything within reach. They might be able to say “mama,” too, although it’s completely normal for babies to go months longer before they start saying recognizable words. 

Taking a stand for independence.

All babies develop at different rates. In general, by the end of your baby's ninth month, they will likely be able to:

Pull themselves to a standing position 
Walk (cruise) while holding onto furniture 
Use their thumb and index finger to grab objects
Wave bye-bye 
Understand the word “no”

Building up their big brain.

Your baby has learned so much during the past 8 months. Here are some simple ways to help continue to build their cognitive skills:

Read them books while naming and pointing to objects and people 
Play hand-eye coordination games, such as “patty-cake” and “peek-a-boo”

Your baby’s world at 10 months: this little one’s got skills!

At 10 months, babies are typically interacting more with people and showing off new skills at every chance. Help your baby adapt to their expanding world by reciting nursery rhymes, singing songs, and taking them to new places for the first time. 

Let the good times walk.

All babies develop at different rates. In general, by the end of month 10, your baby will likely be able to: 

Walk with you slowly while holding hands 
Say “mama” and “dada” and know what they mean 
Stand while holding onto something 
Protest if you take a toy away 
Play hand games and wave bye-bye

Build their budding imagination.

It’s never too early to inspire your baby’s creativity. Here are fun, simple ideas to spark their imagination: 

Buy or make puppets from old mittens or socks using baby-safe attachments. Make the puppet “talk” to your baby and encourage them to talk back. 
Make a scrapbook of familiar objects such as toys, animals, and family members. Help your baby point to the pictures as you name them. 
Sing them familiar songs and read them nursery rhymes.

Your baby’s world at 11 months: put on your running shoes!

Your baby might be more active than ever and begin to explore their surroundings more. Whether they’re cruising around the living room furniture, standing on their own, or climbing up (but not down) the stairs, consider taking new steps to make your home safe from their curious roaming.

They’re right on track.

All babies develop at different rates, so don’t worry if your baby does something later or earlier than other children. In general, by the end of their 11^th month, your baby will be able to: 

Walk with one hand being held 
Drink from a sippy cup 
Say one word other than “mama” or “dada” 
Point or gesture to ask for something

Bolster baby’s brain.

Eleven months is a great age to nurture your baby’s growing brain and developing hand-eye coordination with these activities: 

Help them walk with (or without) support 
Ask them to find their favorite toy in their toy basket 
Provide push/pull toys for them to play with 
Roll or toss a large soft ball back and forth 
Encourage them to stand and pick up a toy off the floor without holding on to anything

Safety tips for a baby on the move.

It’s a good idea to install safety gates or other barriers at the top and bottom of stairs. Here are some other tips to help keep your baby safe: 

Clear their play area of hard, sharp-edged furniture 
Lower their crib mattress so they can’t crawl out or fall while they stand 
Install childproof locks on drawers, screens, doors, and windows 
Move pots and pans containing hot foods away from the edge of counters and tables
Insert plug protectors in any unused electrical outlets 
Store toxic substances (like household cleaners and products) out of baby’s reach

Your baby’s world at 12 months: a year of leaps

Your baby is developing a personality all their own, and it shows. They’re about to start the physical changes of leaping into toddlerhood, so it’s time to prepare for the next growth spurt. 

Time flies when you’re turning 1.

You’ve both come so far in the first year, and your baby will continue to develop at their own pace. Generally, by the end of month 12, your little one will be able to: 

Take their first solo steps 
Say two words other than “mama” and “dada” 
Speak in “baby-talk” sentences 
Imitate your actions 
Drink from a sippy cup without help

Support brain development.

Help keep your baby’s brain developing through play in social settings and during your individual time with them. 

Introduce them to brief playdates to practice playing in groups. There won’t be much interactive play just yet, but they’ll get used to the playing environment. 
“Read” a picture book together. Identify what you see on each page to help them learn new words and objects.

Prepare to wave “bye-bye” to the bottle.

If your 1-year-old is still on the bottle, these tips could help them transition to a sippy cup:   

Begin to offer them a sippy cup in place of midday bottles
Don’t let your baby roam with the bottle, and limit where they can have it, such as only while on your lap or at the table 
Try offering breast milk or infant formula in the sippy cup. If that doesn't seem to be working, try offering water in a sippy cup with 1 meal per day

Now that your toddler is transitioning to table foods, it can be hard to tell if they are getting the nutrition they need. This might be a good time to add in a toddler drink, like Go & Grow 360 Total Care ^® by Similac^®. It’s designed to help balance a toddler’s diet and support brain, eye, and physical development from ages 12 to 36 months.
