If this is your first time, you might be uncertain of what you can expect at different ages. Developmental milestones provide a baseline for comparison.

However, it is important to note that children develop at different rates. A child's development can be influenced by several factors, including nutrition, their state at the time of examination, and culture. Children of different cultures may develop certain skills at different ages, but most humans develop these skills at some or other stage. Also remember that, until a certain age, premature infants generally reach milestones later than others of the same birth age.
