Baptismal jumpsuits for youth?

I have the opposite issue - I can't find baptismal jumpsuits for children. I see that there's a 2XS, but the sizing chart doesn't show the length of the pants so I'm not sure if buying a 2XS or XS will fit an eight year-old. Does anyone have the link or the item number for children baptismal jumpsuits?

The youth baptismal suit is item 448770502 and found on this page: https://store.churchofjesuschrist.org/usa/en/baptismal-suit-%28youth%29. There is a sizing chart on the page.
