Milestones Monday

A child presents for a routine well-child visit. The parents report that the child can pull to stand, cruises along furniture, uses a pincer grasp to pick up small pieces of food, says "mama" and "dada" specifically, waves bye-bye, and enjoys interactive games such as peek-a-boo. During the visit, you observe the child pick up a small block and intentionally drop it into a container.

Question:

Based on the information provided, what developmental age is this child at?
