Children at wedding / reception

My daughter is getting married June 12, 2021. It's already been postponed twice (third times a charm!) due to Covid. I am paying for the event, I'm divorced from her father and he is not helping financially. The wedding and reception are being held at a beautiful aquarium, which guests will be able to tour during cocktail hour. The wedding is at 6:30pm and dinner won't be served until 8pm. Whew! that's the background.



My question is: my daughter called me today and said that some couples have asked her fiance if they can bring their kids. So far...we are talking about 6 kids all 2 or younger...1 is 4 months old. They are the kids of fiances brother, a groomsman, and another guest. We, especially my daughter, is concerned over crying during ceremony and reception. it's a late night and kids get cranky. I'm ok with them there, but I'm NOT ok paying $60 for a kids entree. If we say it's ok to bring kids, is it rude to make a goodie bag with some treats, or other occupier along with a note with map showing where to go if they get fussy? or just say no kids?
