For us it was a cost thing. Paid for the wedding ourselves. Kid takes the same plate as an adult but won't eat it. Don't remember exactly how it was worded on the invites, but my mother got more than one whiney phone call. Cousin specifically asked if they could bring their two kids. Roll our eyes and of course we say yes and pay for four plates. Who showed up? Mother and daughter. Only.

I trust those of you who insist on bring the 'whole fam dambly' also increase your gift accordingly. Sound mercenary? Oh, okay- so your 'gift' is letting The Happy Couple (or their parents) buy something for you...
