I swear this is included in the “possible disasters on my wedding” list… if u spend a decent amount of money on decor, whats the point if the kids are going to RUIN it! 
… and if they damage something, prolly u’ll have to pay for it!
On my sister’s wedding, this one kid broke a glass and another kid started stepping on the broken glass to break into more tiny pieces 
I stood there for like a few seconds hoping his mom would shout out “stop it!”, but no she just sat there… I looked like a lunatic running after kids telling them to behave! They were on the stage n all, and did do some damage to the setting before the wedding even began! sighhh…
