We are inviting quite a few people who have newborns/infants and I'm not sure how many of them will actually come...just in case...should I place an extra chair next to their parent's tables to sit a carseat on it or something? I'm not paying by the chair or anything...they're included with the venue...I just need a chair count so they can be gotten out of storage.
Also...does 18 months or so seem like a reasonable age for them to get their own chair? 2 maybe?
