Hold up a rattle in each hand. Shake one and see if your baby focuses on it. After a few seconds, shake the other rattle. Wait for your baby to focus on the other rattle. Shifting their gaze between objects shows that babies can focus their attention and vision on objects they find interesting.
Babies at this age are in the sensorimotor stage, where they explore the world with their senses. Exploring objects allows babies to learn about their characteristics.
Their vision is improving during this time, and they can see objects further away. They can also see colours, though they prefer objects with strong colour contrast, such as black, white, and red. With this visual ability, they can explore using their senses and develop motor skills.
Babies who observe objects while simultaneously rotating them are receiving rich perceptual-motor feedback from multiple perspectives.This contributes to their perception that the object is three dimensional. Similarly, babies who alternately mouth and look at objects can integrate tactile and visual information about their properties. Such exploratory experiences allow for object categorisation and hand-eye coordination. Those experiences also lay the foundation for subsequent cognitive and language development.
Babies' very first playmates and toys are their parents and other caregivers. So, interacting and playing with your baby often will help facilitate their healthy development.
