Activity for Krissian

So my FH and I had decided the only kids going to the reception would be the kids participating in the wedding. But I have about about 2 OOTs that have babies. Should I let them bring their babies to the wedding? Babies age are about 1 to 2 yrs old

So I know some people are good with hashtags better than the generators out there. We are getting married next year Sept and I want a cool hashtag. Last name will be Morales..getting married 09 20 18...thanks in advance!
