Sizing
Please double check sizing before ordering. Best way to determine size is to measure head circumference.
Sizing:
There is a little stretch in them but if you are unsure just ask or go up the next size.
To give you an idea Nate's (4yrs) head is 51cm and the L is firm XL is better Amelia's (20 mths) head is 48cm and the S is very firm, M is better.
*ages are only a guide.....
XS 0-3 mths (41cm max)
S 3-6 mths (44cm max)
M 6-18 mths (48cm max)
L 18 mths -2 yrs (50cm max)
XL 2yrs + (52cm max)
