The Wonder Weeks Book

All babies go though the same changes in the mental development at the same time. This is called a mental leap. With each leap, your baby is given the possibility to learn new things. And every baby wants to learn, much less master, these new skills, as learning these makes him master that ‘puzzle’ or ‘chaos’ that is in his brain since the leap. Learning new things helps him to get through the fussy phase and is good for his development for the rest of his life.
