Can I just check something? The seller of those hats recommends that they aren't for everyday wear. Are you wanting a funky hat for cute photos or do you want something more practical?
I've looked on Ravelry and there are lots of patterns for these types of hats including a Santa hat with pompons that hang down from the ear flaps. So cute 
Would it be possible for you to have a look on Ravelry and let me know if there are any that you like in particular. I searched using "crochet beanie" and then narrowing down by "free patterns" and "age-baby".
