Key Baby Milestones For The First 12 Months

Baby milestones - your baby's growth & development for the first 12 months

Watching your little one grow and develop is one of parenthood's greatest joys. From their first smile to those wobbly first steps, every milestone is a precious moment. As your baby grows and changes through their first year, understanding their development can help you prepare for each exciting new stage. Discover our useful guide for understanding your baby's development in the first 12 months.

Understanding Developmental Milestones

Resources like the Raising Children Network and the Royal Children's Hospital Melbourne website provide comprehensive guidelines for understanding how most children progress. While babies learn and develop skills in roughly the same order, they may reach these important skills at different ages.

Our guide covers both fine motor skills (small body movements involving your baby's hands) and large body movements, along with social skills and communication development, and will help you monitor your baby's growth and development through their first year. Remember that babies develop at their own pace. If you're concerned about your child's development, always consult your baby's health care provider, Maternal and Child Health nurse, or local health service.

Tracking Your Baby's Progress

Always remember that child development happens over time. As your baby develops and grows, you'll notice them reaching different milestones at their own pace. While most babies follow a similar developmental path, it's important to remember that each child is unique. If you're concerned about your baby's progress, useful tools like the Personal Health Record (Blue Book/Green Book/Child Health Record, depending on your state) can help you track their development. Your Maternal and Child Health nurse or GP can guide you through these important skills and address any concerns you may have about your child's development.

How often will you need to buy new baby clothing in the first 12 months?

Most babies will typically need new clothes 4-5 times during their first year due to rapid growth. Here's what to expect:

0-3 months

During these early months, babies grow rapidly, often needing new sizes every few weeks! Look for soft, stretchy fabrics that are gentle on delicate skin and accommodate frequent nappy changes. Natural fibres like organic cotton will help to regulate their temperature during varying seasons.

3-6 months

While their growth may slow slightly, babies aged three to six months still need regular wardrobe updates. Choose clothing that allows freedom of movement for rolling and early crawling attempts, as well as easy-access designs to make dressing and changing more convenient for both you and your baby.

6-9 months

Active babies need durable clothes that can withstand crawling. Quality materials become especially important as your baby becomes more mobile - consider pieces with reinforced knees and stretchy fabrics that won't restrict movement.

9-12 months

Walking babies need sturdy clothes that allow for plenty of movement. Choose slightly larger sizes to accommodate growth. Durability will be key as your little one starts to explore their world!

Our tips on preparing for different seasons

Summer

Lightweight, breathable natural fibres are essential for hot summers. Choose loose-fitting clothes to allow air circulation. Sun safety is also crucial, so look for UV-protective clothing and wide-brimmed hats, as well as rashies and swimsuits for beach or pool days. It's also a good idea to have a light muslin wrap handy to act as an extra layer in air-conditioned spaces.

Autumn

Temperatures can vary significantly in autumn, so it's best to layer lightweight pieces. Long-sleeve bodysuits provide warmth without overheating, and light jumpers cardigans are useful for cooler mornings and evenings. Where you can, try to choose transitional pieces that work across seasons.

Winter

In winter we love merino wool layers that provide natural warmth without bulk. Consider warm inner layers, as well as lighter pieces that are suitable for heated spaces and can be removed easily. You'll also need waterproof layers for wet winter days, and don't forget beanies and mittens for extra warmth!

Spring

You'll need to return to layering as temperatures become variable. Choose breathable fabrics that adapt to changing weather and keep sun protection handy as UV levels begin to rise.
