When u buy a carrier to your baby look for a logo of international hip dysplasia institute. Some carrier will have this certification to recognise that these products are safe for a healthy hip development. You can check this website for full list of hip friendly baby carrier https://hipdysplasia.org/developmental-dysplasia-of-the-hip/prevention/baby-carriers-seats-and-other-equipment/hip-healthy-products/
