Every parent has had that moment, watching their child do something new and wondering, is that normal? Should they be doing more of this? Less of that? It’s one of the most common things families ask us, and honestly, it never gets old.
The early years move fast. One week your baby is figuring out how their hands work, and a few months later they’re pulling themselves up on the furniture and giving you a look that says they’re very pleased with themselves. Keeping track of it all, and knowing what to expect, can help you enjoy the ride a little more and worry a little less.
This guide walks through the key developmental milestones from birth to five years, across four areas: physical, language, social-emotional, and cognitive development. It’s friendly, general information, not a checklist to stress over. Every child grows at their own pace, and that’s completely fine. If you ever have a genuine concern about your child’s development, your GP or child health nurse is always the best first call.
What Developmental Milestones Actually Mean
Milestones are broad markers based on research into how children typically develop. They give families and educators a shared way of talking about growth, a general picture of what many children are doing within a given age range.
They’re not a pass or fail. A child can be ahead in one area and taking their time in another, and both are completely normal. Development doesn’t follow a straight line, and it certainly doesn’t follow a strict schedule.
At Aussie Kindies, our educators pay close attention to each child’s individual development. They’re trained to notice where children are thriving and where they might benefit from a little extra support, and they’re always happy to chat with families about what they’re seeing.
Birth to 12 Months: Hello, World
The first year is a whirlwind. You start with a newborn who mostly sleeps and eats, and twelve months later you’ve got a little person who’s on the move, making noise, and very much letting you know what they think about things.
- Physical development: Most babies go from having very little head control at birth to sitting up on their own, rolling both ways, and reaching for everything in sight. By 9-12 months, many are crawling, pulling themselves up to stand, and beginning to shuffle along the furniture.
- Language development: Babies are communicating from the very beginning, through cries, facial expressions, and quickly, lots of babbling. By around 6 months most are responding to their name, and by 12 months many are saying a first word and using gestures like waving and pointing to get their message across.
- Social and emotional development: The first year is really about connection. Babies learn to recognise the faces and voices of the people they love, and by 6-8 months many start showing a bit of stranger anxiety, which, while it can be tricky, is actually a really healthy sign that they’ve formed strong attachments.
- Cognitive development: Somewhere between 8 and 12 months, most babies develop object permanence - the understanding that something still exists even when they can’t see it. You’ll notice it when your baby starts looking for a toy you’ve hidden, or peering around a corner to find you. It’s a big deal, developmentally speaking.
How our educators support this stage
In our baby rooms, everything starts with building warm, trusting relationships. Our educators get to know each baby - their rhythms, their preferences, what settles them and what lights them up. Sensory play, lots of talking and singing, and calm and caring environments are at the heart of how we support little ones through this stage.
1 to 2 Years: On the Go and Finding Their Voice
Toddlerhood is something else. One minute they’re toddling toward you with their arms out for a cuddle, and the next they’re flat on the floor because you cut their toast the wrong way. It’s a big year.
- Physical development: Most children take their first steps somewhere between 9 and 15 months, though some take a little longer, and that’s fine. By 18-24 months, many are walking confidently, having a crack at running, and climbing anything they can get their hands on. Fine motor skills are coming along too - toddlers love stacking, filling, and emptying things.
- Language development: Words start coming thick and fast through this period. Many children are using 10-20 words by 18 months and beginning to put two words together - “more biscuit,” “daddy home” - by around 24 months. It’s also worth knowing that most toddlers understand a lot more than they can say at this stage, so keep talking to them even when it feels one-sided.
- Social and emotional development: This is the age of “mine”, said with absolute conviction about everything, including things that definitely aren’t theirs. Toddlers are developing a strong sense of self, and that comes with big feelings and some pretty spectacular meltdowns. It’s all completely normal and developmentally healthy.
- Cognitive development: Pretend play starts to appear - a wooden spoon becomes a guitar, a cardboard box becomes a boat. This kind of imaginative thinking is a genuinely exciting cognitive milestone, even if it looks like just messing around.
How our educators support this stage
Our toddler rooms are set up for active exploration with just the right amount of structure. Our educators talk with children constantly, narrating what’s happening, responding to their attempts at communication, and building language in the flow of everyday play. Consistent routines help toddlers feel safe and settled, which makes everything else easier.
2 to 3 Years: Big Talkers and Budding Friends
The third year is when language really takes off, and children start to become genuinely interested in other kids, not just playing near them, but actually playing with them. It’s a fun stage, even when it’s noisy.
Physical development: By age 3, most children can run, jump, kick a ball, and go up and down stairs with confidence. Fine motor skills are coming along - they’re holding crayons, turning pages, and starting to have a go at buttons and zips.
Language development: Two-word phrases grow into short sentences between 2 and 3. By their third birthday, most children are chatting in 3-4 word sentences that people outside the family can generally follow. Vocabulary can grow to several hundred words across this period, and you’ll hear most of them, often.
Social and emotional development: Parallel play, where children play beside each other rather than together, is really common at age 2 and starts to shift toward actual cooperative play as they head toward 3. Sharing is still genuinely hard at this age, and that’s not a behaviour problem, it’s just where they’re at developmentally.
Cognitive development: Children this age are starting to get their heads around sequences, categories, and basic concepts of time like “after lunch” or “tomorrow.” And the “why” questions kick in, constantly, relentlessly, about everything. It can be exhausting, but it’s a brilliant sign of a mind that’s working hard.
How our educators support this stage
Our educators create environments that are rich in language and conversation, and they’re deliberate about introducing group experiences that build early social skills. They also do a lot of work around emotional literacy, helping children put words to what they’re feeling, which makes a real difference to how they manage those big moments.
3 to 5 Years: Getting Big Kid Ready
The preschool years are where so much of it comes together. Children’s thinking gets more complex, their friendships get more meaningful, and the foundations for school - reading, writing, counting, listening, sitting still for more than thirty seconds - start to build in earnest.
- Physical development: By 4-5, most children are running, hopping, and skipping without a second thought. Fine motor skills are sharp enough for drawing recognisable pictures, starting to write their name, and using scissors with a bit of guidance.
- Language development: Most children in this range are speaking in full sentences, telling stories with a beginning, middle, and end, and have a vocabulary well into the thousands. They’re also starting to figure out how language works - grammar, jokes, and all.
- Social and emotional development: Friendships are becoming really important, and children are developing genuine empathy and the ability to see things from someone else’s point of view, at least some of the time. They’re also developing a clearer sense of who they are and what they’re about, which is lovely to watch.
- Cognitive development: Early literacy and numeracy are building - letter recognition, counting, sorting, patterns, and basic problem-solving. Play is becoming more rule-based. Children are starting to think logically, make predictions, and stick with something even when it’s a bit tricky.
How our educators support this stage
At Aussie Kindies, our preschool and kindergarten programs are built around setting children up for a confident start to big school. We work within the Early Years Learning Framework (EYLF) and focus on building the skills and confidence children need, not just academically, but socially and emotionally too. We want every child walking into kindy feeling like they belong there.
Every Kid Gets There in Their Own Time
Milestones describe a range, not a deadline. There’s a lot of normal in child development, and most children who are a little ahead or a little behind in any one area are doing just fine.
If something in this guide has made you wonder about your own child, have a chat with your Aussie Kindies educator - they see your child every day and can offer a really grounded perspective. Your GP and child health nurse are great too.
The early years go fast. Understanding what’s happening along the way helps you be present for it, and that’s the most important thing of all.
