Yoshi's Island DS

I need help with getting the character coin in level 2-7. I've been reading the walk-though below, but it doesn't make any sense, because the wind doesn't automatically "flutter"

help!

Flower 3-------- To the left of the ball is another block you can destroy with an egg. Enter that small alcove and jump to reveal a winged cloud; shoot it to get a Key. Next, bounce on the ball to reach the high ledge, and head right. Flutter in the wind to reach the higher ledge, and unlock the door up there. In the room you appear in, hop across the donut platforms to the right. Fly in the wind gust at the far right to reach the top area, then go left. Jump to collect the coins, including two red coins (4), then stand on the donut platforms to reach the Character Coin under them. Once you have it, exit the room.

According to this FAQ, you can make Yoshi 'flutter' by HOLDING the 'jump' button.
