Language
Talking is the next milestone of which parents are typically aware. A toddler's first word often occurs around 12 months, but this is only an average. The child will then continue to steadily add to their vocabulary until around the age of 18 months when language increases rapidly. They may learn as many as 7–9 new words a day. Around this time, toddlers generally know about 50 words. At 21 months is when toddlers begin to incorporate two word phrases into their vocabulary, such as "I go", "mama give", and "baby play". Before going to sleep they often engage in a monologue called crib talk in which they practice conversational skills. At this age, children are becoming very proficient at conveying their wants and needs to their parents in a verbal fashion.
