While many people assume that celebrity parents turn the less glamorous aspects of child-rearing over to their high-paid nannies, they might be surprised to learn that one of the hottest fashion trends among rich and famous parents is the designer diaper bag (also referred to as the "designer baby bag"). Diaper bags have been engineered for both moms and dads, and include separate compartments not only for diapers, but for baby bottles, burping cloths, changing pads, and any conceivable item which will keep baby comfortable while he or she is traveling.

Designer baby bags have all of these conveniences, but they also have style, color, and the kind of materials associated with the fashion elite and style-conscious moms. Designer baby and diaper bags cost more, but have high-quality construction. You can only buy them through boutiques (online and brick-and-mortar), not at mass retail stores. We have put together a description of the different brands, styles, shapes, and sizes of diaper bags from among the hundreds being marketed today.

Here are the latest style trends in designer diaper bags:

Handbag Diaper Bags: Handbag diaper bags both resemble and function as great big handbags, making them the most popular of diaper bags. The handbag diaper bag appeared on the market less than a decade ago, and quickly became a favorite of such celebrity mothers as Angelina Jolie. Heidi Klum, who is synonymous with style, favors the handbag diaper bag. This diaper bag, which normally has medium-length straps and a rounded bottom, is designed to make its wearer appear younger. Handbag diaper bags weigh less and are more streamlined than traditional diaper totes. Their straps are an extra convenience, allowing them to be hung from the back of restaurant chairs.

Totes Designer Diaper Bags: Tote diaper bags are generally considered the workhorses among all designer diaper bags. Tote diaper bags have a boxy design, flat rectangular bottoms, vertical sides, and two shoulder straps. Their simple lines, however, mean that designer diaper bag totes can achieve a certain elegance. They are best used for quiet outdoor excursions, like trips to the park, and many moms store them either in the bottom compartments of their strollers, or else simply hang them from the strollers' handles. While bulky, totes have the advantage of providing the largest number of compartments, and therefore the most space, for baby's belongings.

Messenger Designer Diaper Bags: Somewhat similar to handbag designer diaper bags, messenger diaper bags replace the medium-linked shoulder strap of the handbag design with a removable, extra-length strap which can be which allows the bag to be secured on the back of Mom rather than on from her shoulder. With a messenger diaper bag, Mom will be able to use both hands to control the stroller while taking baby for long walks. San Francisco moms, for instance, will appreciate the freedom of the messenger diaper bag as they navigate those famous hills. Dads are also quite comfortable using the messenger diaper bag, because it allows them to retain a sense of masculinity.

Backpack Designer Diaper Bags: The backpack designer diaper bag is worn on the back just like a traditional backpack, and is extremely popular among parents who like to walk long distances with their babies. One great advantage of the backpack designer diaper bag is that it allows baby to go jogging with Mommy because it does not bounce around as much as other designs of baby bags. The main disadvantage of the backpack diaper bag is that it is simply not as stylish a fashion statement as other designs.

Bowler Designer Diaper Bags: This design of diaper bag is unmistakable because of its round top in short, wide body. Any Mom with minimal bulk and profile in her designer diaper bag will love the bowler bag. They are also very popular among petite women whose short stature is often exaggerated with a larger diaper bag.

Clutch Designer Diaper Bags: Because they are thin enough to be gripped with a single hand, these diaper bags are called clutch bags. Smaller than the other designs of diaper bags, they are equipped, like messenger bags, with fold-over tops and medium-length shoulder straps like those on handbag diaper bags. Lightweight and compact, clutch designer diaper bags have less storage space than other styles, and also wear out faster because they are constructed of less durable materials.
