Overview
When a child is between 12 – 24 months their language starts to develop. Words may not be clear, however very familiar people will be able to understand those first words. Babies first words are often the words they hear a lot, such as ‘bye-bye’, ‘no’, ‘more’, ‘doggy’. Between 12-24 months, your child’s vocabulary may grow to around 5-20 words at 18 months and 50+ words by 24 months. Words at this stage are often single words, and towards 24 months they may start combining 2 word to form short phrases such as ‘more milk’, ‘doggy gone’ and ‘bye bye Dada’.
At this stage, your child will be able to understand simple key word instructions such as ‘where is your nose?’, and at around 24 months, their comprehension increases to understand two key word instructions e.g. ‘give the apple to teddy’.
Advice
Talk to your child to describe what you are doing or what you can see when you are together e.g. “let’s change your nappy”, “that’s a furry dog”, “mummy is putting shoes on”. Any opportunity to talk to your child about what they can see will help them connect words to the world around them.
