Note the contradiction in the following verses.
• Verse Ex02-06 discussing the discovery, by Pharoh's daughter, of baby Moses in a basket states And when she had opened it, she saw the child; while
• Verse Ex02-06 also discussing the discovery of Moses in a basket by Pharoh's daughter, states and, behold, the baby wept. And she had compassion on him, and said, This is one of the Hebrews’ children.

We see the contradiction: Which is it? Did Pharoh's daughter discover a baby or child?

Rashi resolves this using the two aspects method of resolution.
• Moses had the age of a baby but
• the demeanor of a child.

Advanced Rashi: I make the following conjecture: Moses mother knew that if the child cried she would be caught. Hence at the first sign of crying by the child Moses' mother would run to take care of him. This vested a certain regality in the child--for the child learned that by a simple utterance of a cry he would get what he wants. This differs from most babies who cry excessively when they don't get what they want. Pharoh's daughter was attracted to this regality and therefore wanted to raise the child as her own. Hence the dual language in the verse---agewise Moses was an infant but in demeanor and maturity he had the regality of an older child.
