1. Make them bridesmaids and groomsmen.
There's no rule that says your bridal party has to be all adults. This idea works especially well if your children are older than 10 (the typical age cutoff for flower children). If they're younger, then they could serve as junior bridesmaids and groomsmen, but the same idea applies that they participate in activities like the bridal shower (and maybe they're even part of the PG part of the bachelor and bachelorette parties and then head home), and they dress like your bridesmaid and groomsmen.
2. Include your kids in the unity ceremony.
If you're having a unity candle, sand ceremony or nontraditional unity ceremony alternative, this is the perfect chance to involve your kids. By getting married, you really are making one big family, or reaffirming the family that already exists, so it makes total sense. Have them help light the candle, include multiple sand colors or come up with something totally new and creative, like family handprints you can display in your home after the wedding.
3. Write your kids into your vows.
Recognizing your kids in the vows is an easy way to make them feel included and special. It's also important to remind them that you're committing to being a family and not just a wife or husband. You could even engrave a gift with quotes from your vows for them or hang a pretty calligraphed version in your home afterward.
4. Ask your kids to walk you down the aisle.
The person or people that walk you down the aisle don’t have to be your dad or parents. You could switch things up by having your kids walk you instead, and this idea works especially well if your children are older.
5. Have your kids perform.
If your kids are particularly talented in singing, dancing or poetry, for example, you could ask them to showcase their talents in a special performance for you and your guests, even if it's a poem dedicated to you printed in the program.
6. Have them as your flower girl and/or ring bearer.
When it comes to including your kids, you shouldn't force yourself to find a something totally new and different if you want to keep your wedding traditional. This one is classic, easy, simple and a crowd-pleaser.
