Their brains go through amazing changes during the first three years of life. This lesson will highlight cognitive developmental milestones for infants and toddlers.
Milestones at 1 Month
Infants' and toddlers' thinking skills grow as they interact with the world and people around them. As you learned in the first lesson, early experiences matter. Consistent, nurturing experiences help infants and toddlers make sense of the world. Those experiences literally build brain architecture. As infants and toddlers develop, they begin to understand and predict how things work: they open and close a cabinet door over and over, they fill and dump a cup of water in the water table, they bang a spoon on a high chair to hear the sound.
Watching an infant or toddler make new discoveries is truly exciting. Think of how exciting it is the first time an infant stacks blocks and knocks them down or the first time a toddler pretends to "read" a book to you.
