When my son was diagnosed with brachycephaly i searched everywhere for something soft to put in his car seat to reduce the amount of external pressure on the back of his head. I had seen a couple of good reviews about this so gave it a go. I was disappointed with the size of the actual support that goes round the head as it was far far too small, but since he wasnt a newborn at this point i didnt really need it. in fact i ended up cutting it off. What i wanted was a cushioning for the back of his head and this i was delighted with. it's nice and spongy making me feel that his head isn't against a hard surface. So a good product once I'd adapted it myself.
