My child used since it can do the crawl. After a few falls, the helmet was very well protected including the back of the head. Its only flaw is the front guard a bit tight. The vents on top of the head are welcome because after about ten minutes, baby begins to sweat below. It fits perfectly to the skull through effective scratches. I was afraid that the baby does not accept but after six months he continues to put unflinchingly. Very satisfied with the product. I even buy a second stationary with her grandparents.
