By 19-24 months your child should know a bit less than 50 words and will be picking up more regularly. It is important to watch what you say around this time to ensure that your child does not learn unsavory language. A two-year-old may start to use 2-4 word sentences to describe things or explain their feelings.
When your little one does start talking, you can expect words to come slowly at first. Typically, children have around 4-6 words at 15 months and then between 20 and 50 words at 18 months. When your child hits the magic 50 word mark, he will enter a language explosion during which he will astound you with his ability to quickly learn words that you didn't even know he'd heard!
