Fellow blind person here, adding my own anecdote. I click and echolocate. I have two different kinds of clicks. A soft click for very immediate surrounding which I can do rapidly if I need to, and a loud click for figuring out large spaces which I don't use very often for relatively obvious reasons. They're quite helpful for me and especially in new unfamiliar spaces it's almost a reflex that happens on its own unless I consciously try to stop it for social reasons. Just to add another datapoint. What works for one might not work for another, so there's a lot of trial and error involved in figuring out what works and what doesn't. This can be very frustrating sometimes but sympathy will go a long way.
Something I wanted to add, maybe this thread in particular isn't the best place for this but in general, I'm very lucky that my parents did not prevent me from doing things that others may have. For example, I climbed trees, rode a bike, and generally tried to do all of the things my sighted peers were doing. Naturally there were accidents, but not preventing me from doing those things, not preventing me from learning my limits, learning my balance and physical control, getting hurt and getting back up, I believe were absolutely vital to making me the person I am today. I imagine as a parent this can be very stressful or worrying, but I honestly do not believe I would be as independent now if I wasn't allowed to do those things back then. So unless it is absolutely certain that this is something that they will not be able to do at all, maybe consider letting them try it. It will absolutely help confidence, self worth and skills for later independence that are very, very, very badly needed and very easily missed.
I'm not a parent however, so of course take this with a grain of salt. My experience may be slightly biased here.
