Baby bonnets are a must to keep the little one's heads warm and these creations by Etsy user Geekling are over-the-top geeky with designs that emulate some of the most popular sci-fi and comic characters.

Intricately crocheted, the bonnets are expertly crafted with both comfort and style in mind, which means that while they were indeed cute to look at, they'll also help protect baby's noggin. These are great for giving as gifts to new parents who are avid sci-fi fans or even a fantastic purchase for dad to make to help add a little of his own personality to the new arrival.

What's more, the bonnets are available in a size range from newborn to XL, which will fit an eight year old's head or even an adult with a small hat size.
