Usia anak-anak adalah masa yang tak dapat diputar ulang. Inilah saat ketika tulang mereka tumbuh kuat, urat mereka terbentuk dan imajinasi serta kreasi mereka terbang ke angkasa. Seorang penyair Chili, Gabriela Mistral pernah berkata:

 

We are guilty of many errors, but our worst crime is abandoning the children, neglecting the fountain of life. Many of the things we need can wait. The child cannot. Right now is the time his bones are being formed, his blood is being made, and his senses are being developed. To him we cannot answer ‘Tomorrow’. His name is ‘Today’.
