If a child’s language development is delayed or underdeveloped, this may be an indication of hearing problems and could be a reason to consult a physician. Early signs to look for impaired language and possibly social development are lack of cooing and babbling during infancy, followed by the lack of a child beginning to string syllables together and eventually forming simple words. Later on, successful language skills contribute to effective reading and comprehension skills, as well as problem solving and social interactions.

In our guide, you’ll find tables listing specific developmental milestones for each category, including fine and gross motor skills, self-care, cognitive abilities, and language development, as well as others. We strive to increase the understanding that these milestones are only a guide, and that because each child is unique the age at which they reach these milestones will vary. Each page of the guide includes a section listing the age, including years and months, at which children typically develop the particular milestone.
