Why early oral development in babies matters
What to expect in your baby’s oral development journey
0–6 weeks
Primitive ‘suck-swallow-breathe’ reflexes keep your baby safe and nourished. These survival responses lay the groundwork for later, more advanced oral functions.
6+ weeks
By now, your baby is cooing, smiling, and bringing their hands to their mouth — a crucial step for oral development. Consider minimising pacifier use and introducing chew toys to help activate those tiny jaw muscles.
3+ months
The tongue starts poking through the lips as it develops strength and movement. Make sure your baby is getting plenty of tummy time to build neck strength and allow gravity to work on the forward growth of the jaw.
4+ months
Your baby explores different shapes, sizes and textures in their mouth, sending oral sensory information to the brain. Chew toys help activate the chew reflex before solids are introduced.
6+ months
Teething starts, the first teeth erupt, and your baby begins exploring solids. They’re showing a lot more interest in watching you eat and will be keen to try this process themselves.
12–18 months
Your baby should be breathing through their nose and keeping their mouth closed while chewing. They will soon have their 2-year-old molars and be capable of more complex rotary chewing actions. We can now see how the jaws are coming together.
Chewing is more than just a milestone for your baby. It's a vital piece of their early developmental journey

Did you know?
Breastfeeding
Breastfeeding isn’t just about nutrition. The act itself is a complex synchrony of nerve information that coordinates over 26 muscles, helping to grow the jaw and support facial symmetry.
Gag reflex
At around 4 months old, your baby will often stick their fingers and toys far into the mouth until they gag. This is entirely normal, helping to develop the gag reflex that will stay with them for life.
Understanding space
The mouth is where your baby first learns about three-dimensional space. Putting everything in their mouth gives them a lot of feedback about the size of things.
Sensory learning
One-third of all sensory information relayed to the brain comes from the mouth as there are a lot of sensors in the lips, face, and tongue.
