My LO was breech. At 6 weeks old she had an ultrasound due to breech babies being high risk for hip dysplasia. It was a blessing that they checked her, because she ended up having it and I never would have noticed (she seemed totally fine!). She ended up being put in the pavlik brace. I found out yesterday she has another 7 weeks to go wearing the brace. I just want her to be free to roll around and wear cute jammies! I know it is helping her and she will be able to walk properly. She has been wearing it for 11 weeks now.
