For a parent to help their infant develop an early age self-esteem, then the parent could: give the child puzzles, coloring books, and other things that a parent would usually give their child... but the purpose of this, is not only to ceep the child preoccupied, but for the child to feel like he/she is acompleshing something important... especialy if the parent makes a bit of a fuss over how good the accomplishment is... Also, the parent should defenetly give their child enough attention, so he/she doesn't feel neglected or unimportant. Mainly, the parent should find something for the child to do that is a challenge, but eventually the child can overcome; and therefore feel self-esteem.
