A story I heard at a spiritual retreat seems a good fit here:
A young mom and dad recall the events immediately following the birth of their second child. At the time, the couple already had a three-year-old son. As soon as the newborn was brought home from the hospital, the three-year-old son asked to hold the smaller child. But when the infant was put into his arms, the boy would ask that he be left ALONE with the baby. Understandably, the parents were unsettled and didn't think this was a good idea.
Anyway, a few months went by and still the three-year-old insisted that he wanted to be alone with the baby. The parents put it off as long as they could, hoping that the older kid would forget, but his demands just got more and more persistent. Finally, they agreed to leave the two very young children in a room alone for a few minutes. Standing just outside the room, they listened for anything out-of-the-ordinary, while their son was FINALLY alone with the baby, and this is what they heard:
The two-year-old said to the newborn:
"Tell me what God is like, cause I'm starting to forget."
