Including future niece/nephews in the wedding

They could be pages and simply walk up the aisle.

Instead of doing a flower girl, we are having my FH niece (12 years old) walk down blowing bubbles.. And we're having my 10 and 8 year old cousins help hold my dress train as I walk down, but that's cause its a 10 food train!

The kids will be thrilled to attend the wedding. There is no need to invent a role for them.

That's a good point @muriel

We're having our two dogs in the ceremony too! I would let the kids walk with them, but one of our dogs can be a handful, so we're letting my brother/Man of Honor/groomsman do that task.

My initial thought was something like that, just walking down and looking cute, but I wasn't sure what to call it when we talk to my FSIL about it. I imagined the two boys walking on either side of the 11-year old (I'm sure the baby will be my FSIL), but I hadn't gotten any further than that.

My niece and nephew are ring bearer and flower girl, but we're not doing the sign stuff cause FH and I both think that's horrible 'humor'. My niece is throwing petals and her brother is walking down with an empty box that looks like a ring box. You could always make the older kids junior bridesmaids/groomsmen and then the other two just walk down with just a bouquet, together. I like the idea of them blowing bubbles too!
