Accurately measuring the baby's head circumference is the key. Wrap a soft tape measure around the baby's head and pass it around the most prominent area at the back of the head above the eyebrow arch. This is the head circumference. The head circumference of a newborn is generally around 32 to 34 centimeters, but there are individual differences. When purchasing a hat, refer to the head circumference range indicated on the product label. Give priority to hats with elastic designs, such as elastic riffs or adjustable Velcro styles. These can be adjusted appropriately as the baby's head circumference grows, providing a comfortable fit. This helps prevent the hat from being too tight and affecting blood circulation in the head, or too loose and prone to falling off and losing its protective effect.
