Love the beach at CBR!
That does stink that your DD was too tall for the kiddie area! Sounds like they are very strict about it too... I guess it's good for the little ones so they aren't pushed, shoved and stomped over by a bunch of bigger kids (always a pet peeve of mine at parks) but I highly doubt she would have done any harm there, they should have let her stay!
I do think it is great that they enforce it, because there isn't anything more irritating than a bunch of big kids running rampant around the tiny ones. She is definitely not aggressive and really small for her age. Jay is currently in swim classes so maybe by next time we go he will want to swim in the big pool. He is big for his age, so he may be too tall for the kiddie pool anyway.... It was kind of a bummer, though, not being able to all hang out together.
