Hi there! My daughter had the same diagnosis and has just come out of the harness about 2 weeks ago. I am more that willing to answer any of your questions or if you nees someone to just talk to. I know that when the doctor explained to us what was going to happen with the harness and everything, I was nervous, scared, upset, wanting to get another opinion...But it honestly wasnt so bad and it all turned out really well. So, I'll answer the questions you listed in the OP:
Firstly is it going to hurt her?
It doesnt hurt at all. Audrey was really annoyed with it at first because it restricts movements and she is a very active baby, always kicking and such. What the harness does is keep the hips at a 90 degree bend at all times and rotates them slightly outward. This location promotes correct bone development of the hip socket. The first few days were rough, I wont lie. She was used to being able to move and kick and then she was restricted. I was still on mat leave at the time and I just devoted every second to her. I held her and we had lots of cuddle time. Just made her felt that mommy was here for her and that we would get through it together. After a couple of days she just sort of accepted the new change and wasnt as annoyed by it.
(tip: make sure not to put the straps on too tight...the doctor who fitted her put them on pretty tight and it was cutting into the fat rolls on her legs, so I immediately loosened them. Also, the straps can tend to rub the backs of the legs and under the arms, so I got moleskin, the stuff runners put on their feet to avoid blisters, and placed in on the straps where it was rubbing)
Will i have to buy bigger clothes for her so they fit under it?
We live in Hawaii, so luckily for us the weather wasnt an issue. We just kept her in onesies the whole time. She was (and still is to a certain extent) in newborn clothes and so I just used all the newborn ones I had. A couple times when we went somewhere I knew it would be cold, I put pants on under the harness too...this just makes diaper changes more difficult. I found that the the more tight fitting pants were better because they had less opportunity to bunch up under the straps.
Can you tell that she will be wearing one if you didn't know?
Yes, it is worn over the clothes. If you were to put it under the clothes directly next to the skin, it would rub a whole lot more. Over Christmas and New Years and for church on sundays, However, I would put a plain onesie on, then the harness, and then a dress over the harness (I had to use 0-3mo dress though because the newborn size wouldnt fit over the harness)
This is a vanity question- but I have bought her lots of gorgeous little outfits, like leggings and things, will she be able to wear them or will they not fit?
I did the same thing and was very upset that she wouldnt be able to wear them. Lucky for us, she is a skinny little baby and still wears a lot of her newborn clothes and some 0-3mo stuff. So she didnt outgrow anything, but she didnt wear much of the fancy stuff while in the harness (except for what I told you about the dresses) Technically you can put anything under the harness, it can just get bulky and it it bunches up next to her skin I suppose it could hurt or be annoying..
Does anyone have any success stories?
Her hips started with angles in the low 50s and after the 4 weeks were in the high 60s/low 70s. This was enough improvement for the doctor to allow her to come out of it and we just ahve to come back for periodic checks to make sure that they condition doesnt redevelop. We got used to her wearing it and it just becomes routine...its really not as bad as it seems at first. I figured out how to BF, swaddle, do all the normal things we were doing before the brace.
How long did your baby have to wear it for?
Audrey was in it for 4 weeks and 3 days
Tips: Ask your doctor to give you two harnesses...they get dirty really quickly and so youll want to be able to switch them out to wash them. Also, try to keep the harness on as much as possible...I talked to some people who took their baby out for an hour a day to stretch, and their time in the brace was much longer than Audrey's. We only took her out for a bath every other day and for clothing changes. We even changed her diaper with it on...though you wouldnt be able if you were putting pants on the LO. Also, the contraption is confusing with all the stranps and such... I never undid all the straps, or it can be hard to get it all back on right. To take it off I would undo the straps around her legs and simply slide her leg up and out of the leg harness without undoing the strap that connects to the chest strap. If you undo every strap every time you change clothes and such, youll forever be trying to make sure its all back together properly.
Hope this all helped! And, like I said, you can feel free to ask me anything you are wondering about or just talk if you need to. You and your LO will get through this, and the time will go by faster than you think. In the end youll be happy that they caught the problem early and that youre probably avoiding hip problems in the future!
Here are a couple pictures of my LO in the harness, in the dress she is wearing the harness underneath and you really cant tell:
