When planning our wedding my Fiance and I decided that we wouldn't have kids at our wedding it starts at 7pm my Fiance's sisters decided that they didn't want to bring their sons , with them and their husbands in the wedding party it was too much and they wanted a night "off". So after that was discussed my FI and I said no kids. Well his cousin just got pregant and is expecting in May, she told my FI that she was going to come to the wedding with the baby ( now she does not know we are not having kids) . My FI and I do not know what the appropiate way to handle this is, since she essentially has no one to watch the new baby they live in Georgia and her husbands family lives out of the country. How do we handle this?
