It's looking likely that my baby dd is going to need to wear one of these for hip dysplasia. I am so worried. Has anyone had experience with them? I can't grasp how you're supposed to change and bath babies with it on. Won't it get filthy? How do you dress them in it? Any advice appreciated. I know it's necessary and hospital will advise but it's best to hear from people who've gone through it themselves. Thank you.
