If Jamilla is using two-word phrases like "drop ball," she is likely how old?

The use of two-word phrases such as "drop ball" typically indicates a developmental milestone that occurs during the early stages of language acquisition in toddlers. Children generally begin to combine words around the age of 18 to 24 months. At this stage, they are transitioning from single words to more complex speech patterns, enabling them to express simple ideas or requests.

At 12-18 months, children are usually still at the stage of producing single words and may not yet be forming two-word combinations. By 24-30 months, children often begin to use more complex sentences and a wider range of vocabulary, indicating they have progressed past simple two-word phrases. Therefore, the age range of 18-24 months is the most appropriate for Jamilla's use of two-word phrases.
