How does your babys’ world change during a mental leap?

baby_toy_mouthWith each mental leap that your baby makes, it gains a new kind of perception. It is through this new potential or ability that he is able to perceive new things—that is see, hear, taste, smell and feel new things. All the new things he is perceiving now were already present in the environment before the leap. He just did not notice them because his brain did not make them out at the time. After making the mental leap, he suddenly notices the new things in front him. It is difficult for us adults to imagine this, but your baby's whole world has now changed.


Your baby's mental development is very important and significant. It affects not only your baby's mood, but also his health, his intelligence, his sleeping pattern, the three C’s (crying, clinginess, crankiness), and much more. Once you understand your baby’s mental development, you can help your baby in so many ways. If you would like to learn more about the mental development of your baby, order a copy of The Wonder Weeks, which is based on international research.
