This is where it all begins and where we start to interact with the world. Developmental milestones occur in the first year when babies learn to focus their vision, reach out, explore, and learn about the things around them. Cognitive development means the learning process of memory, language,  thinking, and reasoning. The way we cuddle, hold, and play with baby will set the basis for how they will interact with others. The touch and feel of our baby toys help to enrich these milestones.
