Yes! The Zipadee-Zip is designed to remain loose throughout the legs and body which promotes healthy hip development and prevents hip dysplasia. The Zipadee-Zip also accommodates little ones with hip dysplasia who wear a brace while sleeping. Tip: If your baby wears a brace at night, order the Zipadee-Zip size that your baby wears normally; there is no need to size up to fit the brace.
