Good Morning S.. My oldest daughter is now 8 and she was in pageants from about 3 months until about 6. At 6 the whole pageant scene changed into putting lots of make-up on the kids and making them into little adults and I pulled her out. She still has all her trophies and never failed to pull 1st prize or twice she got 2nd prize. Just a few things I was told, most pageants have rules listed, but if they are in diapers, they must have frillys to cover the diapers under their dresses, must have socks NOT tights or panty hose, curls in thier hair or at least matching bright bows should be in their hair if at all possible. Until she walks, you will carry her to the 3-5 points on the stage (they'll be glad to tell you where, so don't worry). You will most likely have a photo side also, so put your photos on a mat and make them not all posed perfectly (like not all Olsen Mills or whatever) example, maybe a photo with her bright eyed staring at bubbles around her or a soft sleeping picture. etc. Most the dresses you can either buy off line (normally cheaper and you can get matching socks also that way) or some local stores offer them for about $100-$150.
Good luck with your little beauty!! God Bless.
