Speech and language development milestones relate to receptive
language (the ability to understand words and sounds) and expressive language
(the ability to use speech and gestures to communicate meaning).

In the womb, babies hear and respond to familiar voices.
Soon after birth, your baby starts to learn expressive language skills. Around 6 to 9 months of age, most babies begin to make the link between sound and meaning. By 12 months, they may have mastered a few words and usually understand far more.
