I'd say, yes, everyone has faced this issue, which is why they make tub spout covers now! There'd be no market for them otherwise!
I didn't have the problem but I did have the padded spout cover just in case. It wasn't a problem when I supervised my son, but he was the only one in the tub so it was easier to position him at the other end. I think parents who save time and water as well as increase the fun by bathing 2 kids at once (all good things) have to be more vigilant because, by definition, one kid is always closer to the spout.
