Is sterile Water for Inhalation safe for drinking?

Irrigation water may be potable, but it is not sterile. When in doubt, boil the water for baby.

Answer 2: Unless you are in a dire situation such as a third world country or lost in the woods (which I doubt as you are using the internet) Do not give an infant or child any water that is not from a safe potable tap (such as your kitchen water faucet, if the water in your area has been deemed safe for human consumption), or from a factory sealed, drinking water.
