When you take your toddler to a well-child check-up at the pediatrician s/he will certainly ask you how many words your child says. The developmental milestone that they are looking at is your child’s spontaneous use of words. These are words your child says not in imitation. If your child points to a dog and says “dog,” that is spontaneous. If you ask your child, “What’s that?” and he says “ball,” that is spontaneous. If your child repeats a word s/he overhears or says a word when you tell him or her to say it, then it’s imitated.
The most accurate way to keep a count of your child’s spontaneous words is to maintain a written list and add to it every time you hear a new word. The chart below can be printed and used to track your child’s early word acquisition. If your child reaches 50 words that s/he uses spontaneously before his or her second birthday, you can stop counting. Children should have a minimum of 50 words in their vocabulary by their second birthday. If your child does not have 50 words by age 2, you should seek a speech-language evaluation from a speech-language pathologist or a developmental evaluation through your state’s early intervention program.
