Who would you call?

I would probably just label her the escort to [insert names of children]. I probably wouldn’t have her try to hold a bouquet if her job is to wrangle small children down the aisle. I’d imagine she’d want both hands for that. You can maybe do a corsage, but I don’t think it’s necessary since she’s not actually part of the bridal party.

Page wrangler. 😆 I’d probably just put her directly under the boys as “escort” or “escort to page boys.” Definitely no bouquet since her job is to child wrangle and she might need hands. I’d give her a corsage to indicate a special position.
