Back when I was in full-time ministry (at least full-time pastoral ministry), I was a Children’s pastor for a church of about 8,000 people and we had well over 800 elementary age students per week. We didn’t need any tools at that stage, but it largely depends on how they are running the children’s ministry (ours was a “kids church” setting that broke up into small groups after the main lesson but in the same auditorium so there was tons of flexibility; the “rotation” was “school-year” volunteers and “summer-break” volunteers and we usually had to force that summer break on the school-year volunteers ). If you are smart about how you setup a children’s ministry and how you pick your curriculum, you pretty much just need to track who is a children’s ministry volunteer and whether or not they have had a background check and been through the baseline training (policies and anti-grooming at the very least), both of which are mandatory before being in the same room as kids.
Unfortunately, if you are handling IT, you probably aren’t in a place where you can influence how the children’s ministry works. Shorter rotations for kids is bad for every stakeholder for a whole list of reasons. I wouldn’t go out of my way to enable it; rather, I’d let them do their thing until they recognize they need to re-think the approach or until you guys hire a children’s pastor and they come in and start to change the approach.
