Children develop language skills at their own pace, but there are general milestones that most children reach by certain ages:
By 12 months: Children typically say their first words and can understand simple instructions. By 2 years: They should be able to form two-word sentences and understand simple questions. By 3 years: Children usually form short sentences and can follow more complex instructions. By 4-5 years: They can construct full sentences and understand more detailed stories and questions.
