if they are what I wore and am thinking about she will have shoes that have a clip loop or attachement hole. then elastisized "belts" that attach to the shoes and wind around her legs in a spiral upwards where they will be attached to a loop on a wide waiste band. When I wore them I was in paain because it was basically pulling my legs and muscles in the opposite direction then they were pointing and also realigning my hips. For the most part being active playing and so on I could ignore the pain. I was older than your daughter so was very aware that it was the braces causing the pain and threw many temper tantrums to get my family members to take them off. Being your daughter is only 18 months old her bones have not grown completely together or into the joint suckets so she might not even experience the pain of bones being turned and held in the right position in the sockets and so on. but if so keeping her as active as possible will help. And hang in there. Its best that she have them now then when she is older and by having them now at 18 months you and she may not have to worry about what and how the kids in school react to her because this might take care of the problem before then. and she might not be in braces then.
