What behavior is common at 15 months of age?

At 15 months of age, it is common for children to begin using a cup as part of their developing fine motor skills and self-feeding abilities. At this age, children are typically transitioning from bottle-feeding to cup usage, which is an important milestone in their development of independence and coordination.

Using a cup demonstrates a grasp of basic motor skills, including the ability to hold an object and bring it to their mouth without significant spilling. This behavior showcases not only physical development but also cognitive growth, as the child begins to understand the purpose of utensils in feeding.

In contrast, speaking in three-word sentences typically does not occur until later stages of language development, around age 2. Counting to ten and hopping on one foot are also milestones that are usually achieved at older ages; counting is generally seen in children closer to preschool age and hopping typically develops around age 4.
