I have two children and I would say they are quite involved with the day and our planning. My daughter chose her dress and picked which tiara style she wanted. My son went with my H2B to help pick the suits and my daughter has been on planty of shopping trips with us and she has given us her opinion on things. They are both going to let us know any songs that they want played and are also going to sign the register as extra witnesses. During the line up they will be standing either side of me and my Groom so we can introduce them to people that they don't know. They are also going to write a speech about how they feel about us getting married, which someone will read out and I'm going to mention how beautiful my daughter looks during mine - my son doesn't want me commenting on him. ?
I'm so proud of my children and the fact they will be sharing our special day with us makes me so happy, Sorry to go all fluffy.
