So I got an email from an old college friend letting me know that he and his wife are attending the wedding and just dropped the RSVP in the mail. He also said that they will be leaving their 2 year old with his mother, but wanted to know if it would be OK for them to bring their newborn (to be born next week..) b/c his wife wont want to leave him that soon (one month old). We explicitly stated on our wedding website and in our invitations that our wedding celebration is an adults-only event. I would really like to see my friend, but I think that if they cant bring the baby they wont come. I'm quite sure that his wife probably wont let him come alone since his ex-girlfriend is one of my bridesmaids. What should I do???
