FBAR for a Kids Saver account

Hi all,
I'm working on my FBAR.
Last year, I opened a Kids Saver account for my son, who is a dual US-UK citizen. It's a standard child's saving account (not an ISA). It has a low balance at the moment (under the threshold).
Nevertheless, as I typically file FBAR, I believe I need to report this account, and I believe this account should be filed in Part IV "Financial Account(s) Where Filer has Signature or Other Authority but No financial Interest in the Account(s)."
And I believe in line 43 "Filer's title with this owner", I should write "parent". Does anyone have experience with this?
Many thanks for all your wonderful advice!

This is exactly what I do. Haven't had any problems yet. But if you believe the internet, seems like this is just a huge pain in the ass for those of us that try to follow the law, but nobody in government is actually doing anything with this information. But of course, the internet could be wrong.

Also, if you haven't already done so, write your Congress people and ask them to support legislation to end the ridiculous taxation system that America has
