I'm not traditionally a fan of changing dresses in the middle of a wedding, and I really do not want to have to change for any reason. However, I've been thinking it may be a good idea to purchase an inexpensive 'party' type cocktail dress that I could possible change into in case anything happens (ie. wine spill, or what I am most worried about, spitup/vomit from holding my son who will be a year and a half old). He generally has no problems and very rarely spits up now (still on formula, no solids yet) but as a new mom I've learned to be prepared for anything, and I'm certainly not going to avoid holding my baby on one of the most important days of our lives. Has anyone else done this? And if something did happen would I need to explain why I changed or just let everyone think it was planned?
