How are you including your kids in your ceremony?

I have two daughters (16 & 10), and I want them to both walk with me.

My daughter who is going to be 10 and my son who is going to be 7 (both from my previous marriage) are included as a junior bridesmaid/ junior groomsman. We also are doing a love lock ceremony in which FH and I will be putting a lock on a tree of life and intend to include the kids adding their own lock as well. I wanted FH to recite vows to the kids in addition to our own but he isn't a fan of too much public speaking so I am not sure if he will or not. My daughter wants to read something to him as their own vows to him for joining the family... but have not figured too much of those details out yet.

My oldest son, who is 10 is my FH's best man. (He's going to be his step-son, but we recently changed his last name to that my FH's.)

My daughter is a year and a half and she's my flower girl. She is going to ride in the wagon that will be pulled by my niece.

I have two kids (10 and 8). They will be a groomsman and bridesmaid respectively. My daughter wanted to wear a "poofy" dress but wanted to be a bridesmaid and not a flower girl so I found a dress with tulle on the bottom but the same fabric as the other bridesmaids on top. My dad will be walking my down the aisle, but when asked, they all will say they are giving me away -- though I hate that saying and am changing it to "who gives their blessing for this marriage?" or something like that. We are also doing a frit ceremony as a unity ceremony including them.

My son who will be 14 when we get married is walking me down the aisle and then will be a GM. My 12 year old daughter is one of my MOH and my FH 15 year old son will be one of his GM. We are not sure if we are doing any kind of unity ceremony or not.
