It is surprising to know that babies in the first 3 months of life can only see three different colors: Black, White, and Grey!!! Their eyesight is not really good and focused. Each day as their eyesight improve you should still put visually stimulating objects around their crib to aid with their thinking process and give them something to look at and give their brains something to process this will also aid with early childhood development even though they can't communicate what they see.
Various colors begin to make themselves visible to babies at the age of 3 months. Babies can now begin to not only see different colors but will be able to distinguish them, however they cannot process them in a meaningful way. Even at an early age expose your babies to vibrant colors that will awaken their senses and encourage them to explore the world around them!
