No kids at the wedding 😅

Ugh I feel like this is such a touchy subject for some people. We’re getting married at my FH’s parents house, and we’ve decided we’re not inviting children other than the 3 kiddos in the wedding party. We’re already squeezing a little tight at 165, granted we know not everyone would make it. Here’s my Dilemma I didn’t print it on the invitations, I totally forgot and brain farted (happens a lot lately 😂) would it be tacky to put a little slip in with the invitations for only people WITH kids with a cute saying that kids aren’t invited 😬 I feel like this is so stressful and I feel so guilty saying no kids. 😭
