I thought so - there isn't any direct scriptural support but as Julia orwell said
Only purpose is to indoctrinate the children. Also to make the parents go out: there's no excuse like, "I couldn't find a babysitter".
Jesus never sent children out in the preaching work and matthew 28 was directed at adults but as punkofnice says the GB in its self appointed capactiy as the FDS (Matt24:45) use such verses to justify making children member publishers alongside adults.
