This specific hat is for 0 - 3 months. It measure about 14 inches around. Because it's crocheted with yarn, it will stretch a bit with your baby's head. The cute bow can be can be retied to adjust tightness.
Check out my store for more options or contact me if you would like a hat in a different colour and/or different size. I have many different colours of yarn!
SIZES are approximately:
Baby 0-3 months 14"
Baby 3-6 months 15"
Baby 6-9 months 16"
Baby 9-12 months 17"
Please note that all babies are different, so to be on the safe side, try and measure the baby's head first. Measure head circumference around the largest part of the head (above the ears and across the forehead). If it's a gift for a baby that's not yet born yet, then the newborn size should fit just fine!
