At 15 months, toddlers are bursting with energy. Your little one’s 15-month-old developmental milestones are all about testing boundaries and exploring new skills.
Every day feels like an adventure as they express themselves more clearly.
This stage often feels like a balance between newfound independence and the need for reassurance from you.
Here’s what you can expect as your little one journeys through their 15-month-old developmental milestones.
Physical & Motor Milestones
Growing Confidence in Movement
Most toddlers are walking well by now, though their steps may still be wobbly.
Some are trying to run, while others experiment with climbing stairs by holding onto furniture or your hand. They may start to bend down and pick up toys without falling over.
You’ll likely see them trying to push or pull objects around the house, a sign of improving balance and strength.
Refining Motor Control
Your child’s coordination is improving every day. At this age, they may try to feed themselves more confidently, even with a spoon.
They might attempt to stack blocks higher or fit shapes into the right spaces.
Scribbling with crayons and turning the pages of a book are favourite activities. These moments may seem small, but they are important steps towards independence.
Language & Cognitive Development
Speech and Early Words
Your toddler may now have a vocabulary of around five to ten words, though this can vary widely.
They may use words like “ball,” “dog,” or “bye,” and often combine them with gestures to get their point across.
Pointing to objects and waiting for you to name them is common, as is repeating sounds or simple words you use often.
Understanding and Problem-Solving
Cognitive skills are expanding quickly. Your toddler may understand simple commands such as “bring the toy” or “sit down.”
They also begin to show early problem-solving skills, like figuring out how to open a container or stack blocks in a way that doesn’t topple.
Repetition plays a big role in learning, so don’t be surprised if they ask for the same story or song again and again.
Social & Emotional Development
Independence and Testing Limits
At 15 months, toddlers are keen to assert themselves. They may resist your help when dressing or feeding, wanting to “do it myself.”
Tantrums can appear more often now, especially when they’re tired or frustrated.
These moments are part of healthy emotional development, as your child learns to manage big feelings while exploring independence.
Connection and Comfort
Despite their growing independence, your toddler still looks to you for reassurance.
They may bring you toys to share, hug you tightly after a fall, or seek comfort in familiar routines.
Stranger anxiety may still be present, but many toddlers are slowly becoming more open to interacting with new people, especially if you’re nearby.
Sensory & Perceptual Development
Exploring Through Touch and Taste
Toddlers love to explore the world with their senses. At 15 months, they may touch and mouth objects more deliberately, learning about textures, shapes, and sizes.
Food exploration continues as they become more adventurous with flavours, though picky eating may also begin to emerge.
Attention and Imitation
Attention spans are slowly growing, and your toddler may sit through a short story or engage with toys for longer periods.
They also imitate your actions more closely—wiping a table, stirring with a spoon, or talking on a toy phone.
These small imitations are signs of healthy perceptual development and growing awareness of the world.
When to Talk to a Paediatrician
Every child develops at their own pace, but check with your paediatrician if your toddler:
- isn’t walking with support or independently by 15 months.
- doesn’t use gestures like pointing or waving.
- shows little interest in imitating sounds, words, or actions.
- rarely makes eye contact or doesn’t respond to familiar voices.
- has trouble eating or swallowing.
Expert Tips & Daily Activities
Active Play Outdoors
Give your toddler plenty of safe space to move, climb, and walk.
A trip to the playground allows them to practise balance and coordination, while walking on grass or sand builds strength in their legs. Encourage free movement as much as possible.
Language Building at Home
Talk to your toddler throughout the day. Label everyday objects, describe actions, and respond to their babbles.
Reading interactive board books and singing nursery rhymes are fun ways to build vocabulary. Use repetition and gestures to support understanding.
Simple Problem-Solving Games
Offer toys that involve fitting, stacking, or sorting. Encourage exploration rather than focusing on “getting it right.”
Activities like building towers or playing with nesting cups support both cognitive and fine motor growth.
Routines and Emotional Support
Consistency in daily routines gives toddlers comfort and security. Set regular times for meals, naps, and bedtime.
During tantrums, stay calm and acknowledge their feelings while gently guiding them back to calm. This helps build trust and emotional resilience.
Embracing the Journey
Fifteen months is a time of discovery, stubbornness, and joy.
Your toddler is growing into a little person with a strong personality, and every day brings something new.
Your child’s 15-month-old developmental milestones are just as special as the previous milestones.
Remember to guide them through frustrations, but also remember enjoy this busy and rewarding stage.
