Language Development
One of the biggest milestones in a toddler’s life is when they first start to use words and display other communication skills, beyond crying. Early language development may look different for each toddler–we do have to remember they are individual people, after all–but here are some key milestones that are expected for each age group:
1 year old: by this time, your toddler should be able to say a handful of words. Of course, this is in addition to babbling, and the key skill of trying to imitate your voice! They are trying to imitate the sounds they hear, and at this age you should be hearing consonants and vowels coming clearly out of your baby’s mouth. You may also notice that they are using hand and body gestures to communicate certain needs or activities, like pointing to their toys for play time or touching their mouth for snacks. This is a normal process of cognitive development, and you can help enhance it by talking to them as much as possible and helping them follow simple directions by associating words with movements, like saying “up” and helping lift them.
2 years old: this is the point where your toddler should have a steady vocabulary they are repeating, and they begin to expand it. You can help them by reading more and more stories to them, or using more advanced language than before. Additionally, they are able to comprehend sentence structure (slowly) and you may see them using two-word sentences and linking words. Building on their conquered skills of body gestures, they are now able to identify objects and body parts and clearly name them. 2 y/os may also exhibit understanding of slightly more abstract concepts, such as using pronouns.
3 years old: your toddler should have advanced to forming simple sentences and speaking clearly by this age. This goes hand in hand with their ability to string multiple words together. You can help expand this skill by repeating their word combinations back to them every time they use them, and model new word combinations to encourage them to try them. Toddlers at this age are also able to use the correct words to identify both objects and needs. Since their cognitive abilities are growing, you will also notice they can follow two part requests like “Please pick up your shoes and put them on the shelf.”
4 years old: this is considered an age when your toddler is turning into a child, so you will see more advanced language patterns emerge– like them creating more complex sentences and annunciating them clearly. Your child should also be able to identify shapes, colors, and letters, especially if those appear on objects they see often. Their ability to understand more abstract concepts will be more advanced, and they start recognizing the concept of time, like moments throughout the day. It is not unlikely that your child can now follow complex requests, and voice their own wants and needs in more complex sentences, or multi-part sentences.
