Hi fellow bride and groom to be’s

I need advice on how to word it on my invites that children are not invited to my wedding (apart from the flower girls obviously)

It’s mainly for their own safety as there is a bit of a cliff edge not too far away from the garden and also they will get bored and I don’t want it turning into nursery!

I just don’t want to offend anyone. There are 2 women that will have small babies (3 if I get lucky!) and thats fine.

Would any of you parents be offended if your child wasn’t invited to a wedding with you ?

Thanks
