Aquaduck height question

Can anyone tell me how strict the aquaduck operators are in enforcing the height limit. I know at WDW the cast members can be very strict and will err on the side of not letting someone ride. My daughter is currently 41 and 1/4 inches and would be devastated if she cannot ride. She has very poofy curly hair so I am hoping that helps as I don’t think she is going to spout 3/4 inches in the next month. Any thoughts would be most appreciated. Thanks

I’m assuming they are just as strick on DCL. It’s a safety issue.
