She had no issues with equalizing, I taught her that in the pool before diving came up so she knew how to do it already. Some children do have issues with it as their Eustachian tubes are smaller and it may be harder or impossible as they may collapse shut before they are able to equaliz, in which case they just have to wait until they develop further.
Junior OW divers are certified to the same standards as OW divers, all the skills are exactly the same but the max depth recommendation is 40 feet. during her last check dive we went down to 40, well 39, for a couple mins so that she could see what it was like at that depth. I plan on keeping things 30 feet or less with her until she is older and has built up some experience.
I have never read anything about bone density issues in children and diving. maybe someone like
@Duke Dive Medicine or
@doctormike can weigh in on that.
