Top products for good price and does what it promises. Have there already been ordered for a friend ind it would recommend. Our son was 4 months old when we bought the pillow. He had always slept on their backs and located on the side and not at all. We ordered it quite late, we doubted that the pillow would cause something. But we had to try it. Only 40-50 we did not want to spend on something that its effect can not promise. That is why we chose this cheaper option and now 3 months later, I can say - it was not a bad buy. Our son has now again a beautiful round head. Too bad that I did not take any photos, "previously". But the difference is visible.
Note: we took and used the pillow case. Not just for sleeping, but also during the day in the rocker, on the sofa, on the floor and in the stroller. You have to constantly push back and forth, so that baby is right on it (turning the baby and the pad puts himself) but well worth the effort.
