Baby Hat 100% Cotton Color: Navy Recommended for the coming season. This baby hat is stretchy. Recommended for babies with small heads. Can be worn by newborns if folded over. My 7-month-old with a head circumference of 42.5cm can also wear it, but it's a snug fit (see image 5). My son has a small head, and other hats were too big, but this one fit perfectly, and we used different colors frequently. No pilling, and it's clean. I hope someone can use it (..◜ᴗ◝..)
