☆ This is a baby rack pillow for babies who tend to turn their heads to one side. It gently fits the baby's neck and relieves tension in the neck and shoulders. It helps prevent head-turning habits and head deformation. I used it for a short period when my child was a baby, as I heard it was more likely to improve the condition than a donut pillow. An unused changing mat is also included. It has been home-cleaned with baby detergent. We have no pets and are non-smokers.
