Reaching the first birthday is a major progress for both you and your baby. As your little one hits their 12-month-old developmental milestones, they officially enter the world of toddlerhood.
It’s an exciting time, full of firsts—first steps, first words, and a clearer glimpse of the personality that will continue to blossom.
But while the year may have flown by, development is still unfolding at a rapid pace. As they approach their first birthday, babies often balance between babyhood and toddlerhood, eager to try independence yet still seeking your comfort and support.
Here’s what you can expect with your little one’s 12-month-old developmental milestones.
Physical & Motor Milestones
First Steps and Standing Tall
Many 12-month-olds are taking their first independent steps. Some may already toddle confidently, while others are just starting to let go of the furniture.
Standing without support, even for a few seconds, is a big achievement at this age.
Every attempt, whether successful or wobbly, is a sign of building strength and coordination. Offer encouragement by providing safe spaces and cheering on their efforts.
More Control in Movement
Beyond walking, babies are refining other movements. Crawling may still be their preferred mode of travel, but now it’s faster and more purposeful.
They may also squat to pick up toys, climb low furniture, or attempt to push and pull objects.
This stage is about practising balance and building the confidence to move more freely.
Communication & Cognitive Development
First Words and Expanding Vocabulary
By 12 months, many babies can say one or two recognisable words. “Mama”, “Dada”, or words linked to daily routines, like “ball” or “bye-bye”, often appear around this age.
Even if vocabulary is limited, babbling continues with more expression, tone, and rhythm.
Gestures play an equally important role. Pointing, waving, and reaching are ways babies communicate before they have more words.
Responding to these signals helps them feel heard and encourages further language growth.
Problem-Solving and Imitation
Cognitive development is blossoming. Babies at this age enjoy solving simple problems, like working out how to open a container or stacking blocks to see how high they can go.
They also imitate daily actions—talking on a toy phone, stirring a spoon, or trying to brush hair. This imitation reflects both memory and understanding, as babies connect what they see with how to act.
Social & Emotional Development
Strong Attachments and Independence
At 12 months, your baby likely shows a healthy mix of clinginess and independence. They may follow you closely, protest when you leave, and yet show pride in doing something on their own.
This balance is a natural part of emotional growth.
Secure attachment gives babies the confidence to explore, knowing you are always a safe base to return to.
Personality Shining Through
Your baby’s individuality is clearer than ever. Some are bold and adventurous; others are thoughtful and observant.
They might show a cheeky sense of humour, enjoy being the centre of attention, or prefer quieter play.
This is also the age when simple play with others—handing toys back and forth or laughing together—becomes more enjoyable. These interactions lay the foundation for future friendships.
Sensory & Perceptual Development
Sharpened Recognition
Babies at 12 months clearly recognise familiar people, places, and objects. They may smile or giggle when they hear a favourite song or eagerly crawl towards a familiar toy.
This recognition extends to routines—your baby may anticipate what happens next when you say “bath time” or “let’s eat”.
Taste and Texture Preferences
Mealtimes are a full sensory experience. Babies may show strong preferences for certain tastes or textures, embracing finger foods while rejecting others.
Exploring new flavours is an important step toward developing healthy eating habits, even if it comes with some messy experiments.
When to Talk to a Paediatrician
All babies grow at their own pace, but seek advice if your 12-month-old:
- has not begun to crawl, pull up, or attempt standing.
- shows little interest in babbling, gestures, or first words.
- does not respond to their name or familiar voices.
- struggles to use hands for picking up small objects.
- appears very stiff, floppy, or withdrawn.
Keeping track of your toddler’s 12-month-old developmental milestones ensures that you’ll know exactly if something is wrong.
If they are not hitting these important milestones, it’s time for a trip to the doctor.
Expert Tips & Daily Activities
Encourage First Steps
Support early walking with push toys or by holding hands. Celebrate every attempt, even if it ends in a tumble.
Boost Language Skills
Name objects, sing simple songs, and read picture books. Pointing to images while naming them reinforces vocabulary.
Play Pretend
Provide everyday items like cups, spoons, or toy phones. Pretend play builds imagination and helps babies connect actions to meaning.
Explore Outdoors
Fresh air and nature walks provide endless opportunities for sensory learning. Babies delight in watching leaves move, listening to birds, or feeling grass beneath their feet.

Turning one is a celebration of growth and love. These 12-month-old developmental milestone signals an important achievement for both you and your now toddler.
Over the past year, you’ve witnessed countless milestones, from first smiles to first steps, each one shaping the little person before you.
At 12 months, your baby is ready to keep exploring, learning, and surprising you every day. The toddler years are around the corner, promising new challenges and joys.
With your guidance, encouragement, and love, they’ll continue to thrive in this exciting next chapter.
