A 1 day old baby is already doing more than most people realise. They recognise your voice from the womb. They root for milk within minutes of birth. They startle at sudden sounds and can briefly focus on your face. Development starts immediately, and it moves fast. This guide walks you through the key milestones from birth to toddlerhood, with practical must-haves at every stage.
What to Expect From a 1 Day Old Baby
In the first 24 hours, your newborn is busy. Their senses are firing. They can smell you, hear you, and feel the difference between skin and a blanket. Their vision is blurry beyond about 30 centimetres, which is roughly the distance from your breast to your face. That is not a coincidence.
What they need most in these early hours is warmth, skin-to-skin contact, and feeding on demand. Colostrum, the thick first milk, is packed with antibodies and exactly what their gut needs before your full milk comes in. For guidance on early feeding, the Australian Breastfeeding Association has thorough, practical resources.
Getting your essentials sorted before birth makes those first days far less stressful. Our guide on what to buy before baby arrives covers the key items worth having ready at home.
The Newborn Stage: 0 to 3 Months
Your baby spent nine months in a warm, dark, snug space. The outside world is a lot. The first three months are often called the fourth trimester because your baby still needs that same closeness, warmth, and rhythmic comfort to settle.
Key milestones in this stage
- Follows faces and high-contrast patterns with their eyes
- Starts to smile socially around 6 to 8 weeks
- Lifts their head briefly during tummy time
- Responds to familiar voices with coos and small sounds
- Begins to show preference for primary caregivers
Must-haves for 0 to 3 months
- Fitted bassinet or cot with a firm, flat mattress that meets Australian safety standards
- Swaddle wraps in breathable fabric to help settle startle reflexes
- At least 6 to 8 onesies and sleepsuits in newborn and 000 sizing
- Nappy essentials: nappies, barrier cream, and plenty of wipes
- A baby carrier or wrap for hands-free settling during the day
For safe sleep setup, follow the guidelines at Red Nose Australia, the leading authority on infant sleep safety in this country.

3 to 6 Months: Becoming More Interactive
This is often the stage where parenthood starts to feel a little more reciprocal. Your baby laughs. They grab for toys. They recognise you from across the room and light up when you walk in.
- Rolls from tummy to back, then back to tummy
- Reaches for and grasps objects
- Babbles and experiments with sounds
- Starts to bear weight on their legs when held standing
- Shows clear interest in faces, mirrors, and bright objects
Tummy time every day from birth builds the strength needed for rolling and eventually crawling. If your baby resists it, try placing them on your chest while you recline. For simple activity ideas that support development at this age, see our article on things you can do with your newborn.
6 to 12 Months: Moving and Eating
This stage is full of firsts. First solid foods. First time sitting unassisted. First crawl. First pull to stand. Your baby is becoming mobile and curious, which means your home needs to keep up.
- Sits without support from around 6 to 7 months
- Crawls or shuffles by around 8 to 10 months
- Starts solids, usually from 6 months with guidance from your GP or child health nurse
- Pulls to stand and begins cruising along furniture
- May take first steps anywhere from 9 to 15 months
Solid foods introduce textures and flavours alongside milk feeds. Raising Children Network has an evidence-based guide to starting solids that is worth bookmarking.
12 Months and Beyond: The Toddler Transition
Around their first birthday, most babies are walking or close to it. Language is building quickly. Tantrums are beginning. Independence is something they want, even when they are not quite ready for it.
- First words typically appear between 10 and 14 months
- Walking solidifies between 12 and 18 months
- Starts to show preferences, point at objects, and follow simple instructions
- Begins parallel play alongside other children
Every baby moves through these stages at their own pace. The ranges above are general guides. If you have concerns about your baby's development at any point, your maternal and child health nurse is the right first call.
