Having just my dad walk me down the isle was not an issue with us, thankfuly... as my mom can be a bit pushy and self-centered sometimes. She was so much more of a bridezilla about everything than I was (Momzilla?). But, I wanted to make sure both my parents and DH's parents were recognized in our short ceremony so, we ended up doing something similar to what moemarsita suggested. We put this in our ceremony:
"Since the dawn of man, people have been united in marriage in all lands, all cultures, and all religions. In marriages everywhere, this is a time for two individuals to leave the families that raised them, to begin a new family. At this time, we ask the parents of the Bride and Groom to come forth to bless this marriage.
Do you, Paul, Arlene, Mark and Janice, who have lovingly raised and nurtured these two individuals, offer your blessing for their marriage, promising to support them, guide them, understand them, and encourage them in their solemn endeavor, in the years ahead? If you agree, please say, "We do". (Parent's respond.)"
We didn't tell our parents we were doing this and it was a nice surprise. BTW, we didn't write it, I took it from another ceremony I found online, I can't remember where.
It's a relatively minor way to have both parents participate. But, as much as you love her, she needs to be gently reminded that it's not her wedding. My mom had to be reminded more than once, and not even by me every time. Both of my brothers had to tell her to back off a few times. We all were patient about it, no matter how frustrating it was, and it avoided fights.
emmssk8s: my prayers are with you and your mom. I hope she responds well to treatment and can be there for your big day.
Good luck!
