I have to disagree and warn against this. Yes the waves are small when they get to the back but the wave tanks filling cause the undercurrent to be very strong knocking a lot of small children over. The bottom of this pool at the end is concrete and rough and if your child falls you are almost guaranteed a cut and or road rash. If you have a toddler or young child even 7 or 8 or maybe older depending on their size and balance... make them wear a life jacket weather they are can't are good, great, amazing swimmer... this will protect them if they fall from getting cut... and if they go out further and are dragged out as it is unlikely at the end they will dragged out but they may be dragged a few feet if they fall scrapping against the concrete..... My son can swim so could his cousin... son was 9 made him wear a life jacket and yes he complained... cousin was 7 he can swim.. no life jacket needed OK we spent an hour at first aid office.. no big deal but lesson learned...
Each to their own, but I would disagree with you. Well, I do agree that the bottom of the pool is rough...I've had a few "road rash" type burns on my knees (my kids think it's hysterical when I hold them up over my head as a wave is coming...leaves me defenseless and I get hit smack in the face/chest by the wave). However you are far from guaranteed a cut simply if you fall. If you get dragged, you might get a burn, but it's not like everyone who goes in there walks out a bloody mess (I know that's not what you said, but you know what I mean). I also disagree that the filling tanks create some huge undercurrent. As with any big waves, there is undercurrent out deep, but sorry I just haven't seen little kids get sucked in when standing in 2" deep water. In fact, there's an entire kiddie section for toddlers right off to the left of the pool (as you face the waves), and the water there gets choppy too as waves come through. I've seen people fall from the undercurrent when they're in somewhat deeper water (I'd guess 18+" deep), but even then it's not like they get sucked out to sea...they fall and get back up.
To me, it's all about common sense...and I guess how each parent feels about having their kid in the water. My kids are good swimmers, but not on any swim teams. I've had them in that wave pool since they were toddlers. Of course, when they were little, they were confined to shallow portions of it. But since they were about 7, they've been out in water up to their waist braving the waves, no life jacket. Can't count how many times we've been in it, it's one of their favorite things. We've all had a rug burn or two, but nothing beyond that.
The wave pool can be VERY intense, and very dangerous, no doubt about it. If you go out to where the water is 4+ feet deep when calm, you need to be a really good swimmer. If you do something foolish, either with yourself or your kids, it can be a danger. However, I just don't agree when people say that young kids should avoid the pool completely. Being zero entry by definition means there's a part of the pool where the water is literally only an inch or two deep. Common sense will keep you safe. The back of the pool where you enter is very gentle (the water, not the concrete), even for a toddler.
Frankly, I could argue the BB pool is just as dangerous. Yeah, the waves are much smaller, but they're constant and unrelenting. If you're not a great swimmer and go out to where it's hard to stand, it can be pretty easy to get overwhelmed by the constant waves. Don't get me wrong, I have no problem with that pool either, I really enjoy it. But my point is both pools present a danger...as any pool does, just in very different ways.
