A new born baby is held up right with their feet touching the ground, they will make movements as it tries to walk.
Intellectual- during the first 18 months infants have to coordinate their senses and muscle behaviour. 1-2yrs infants do not understand that an object exists unless it is in their view. 2-7yrs children do not think logically.
Babies explore by sucking toys, fingers, clothing, and so on. In this way they can get an understanding of objects.
