To sign blow, take your modified O hand from your lips to a foot or two in front of you, as your closed hand opens up into a number 5 hand. It is exactly as if you are blowing air onto something.
Teach your child the blow sign when their food is hot, when blowing out their birthday candles, when you are blowing bubbles, or when you are describing what the fan is doing to the air in the room.
Teach your child this sign in the context of real-life situations: blowing on hot food, blowing out a birthday candle, or blowing bubbles or dandelions.
