Paradise Pier water slide - height restrictions?

[disney-super-mom]

Is there a height restriction for the Paradise Pier water slide? I wanted to know if our 3 year old could go down it?

I know they didn't have a height restriction at the Disneyland Hotel pool slide when we stayed there in 2004, but they did make our oldest, who was at that time 5 years old, take a swim test to make sure he could swim unassisted. But, since the Paradise Pier pool slide doesn't empty into an actual pool, I didn't know if there were any kind of restrictions on who can use the slide.

Thanks for any info you can give me about this.
