I too was wondering how there could be such a hype on pajamas. Then I decided to give these a try and I totally understand. We have all other brands of pajamas including carters, Hanna Anderson, Burts bees, etc. These beat all when it comes thickness and soft material, even after washing a few times they are still extremely soft. My son is 14 months and he fits perfectly in 2T with a little space toGrow. I’d order one size up as with most brands of pajamas.See full review
