As a mother of 2 kids and also a dog, and 2 rabbits, but I think we will leave them out of the ceremony for now. I love including kids and animals in the day, lets face it, 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 them in the process and on the day.
If you have children, either your own, or kids in the family that you would like to include in the ceremony, then here are some ideas of how to do that.
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.
