Okay...for my flower girl and ring bearer, I am thinking of asking permission of the mother of two children I used to babysit who are brother and sister. There are 6 and 8 years old, which I realize is on the upper end of the age range, but I am okay with it. My concern is that there is an older brother (11) who I feel is too old to be included, and a baby sister (2) who is too young. Is it bad if I just ask the middle two children? I don't want to hurt anyone's feelings, but I also don't want to include the older and baby siblings just out of obligation...advice please?!
