As a mother of 2 kids and also a dog, and 2 rabbits, but I think we will leave them out of the wedding ceremony for now. I love including kids and animals in the wedding day. Kids are total winners when it comes to the cute factor, but also if it is a blended family then it is really lovely to include all of them in the process and on your wedding day.
If you have children or pets, either your own, or nieces and nephews, chosen or otherwise that you would like to include in the ceremony, then here are some ideas of how to include kids and dogs in your wedding.
The one thing to remember is that kids will do what they want during the ceremony, so be open to that, as sometimes it is easier to just go with the flow and let them feel comfortable. They may choose to read and then freak out on the day and you need to be ok with that. I remember once a bride had to breastfeed during her vows and we just went with it and that was ok.
