Why does a baby sleep less during a mental leap?

BabyBedAwakeYour baby's world changes completely and suddenly when he makes a mental leap. He did not ask for it and cannot influence it, but suddenly everything is different. He gets upset and you can see this in his sleeping pattern as well. Each baby reacts differently. One baby may almost stop sleeping altogether, the other sleeps less during the night and more during the daytime, and still another may try to sleep but cannot.


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.
