Slugs and snails and puppy-dogs' tails, that's what little boys are made of! Thank goodness baby showers don't reflect that age-old nursery rhyme! Rather, today's showers for mamas expecting little boys are filled with the same sweet treats and adorable details once reserved for little girls. Check out 14 of our favorite baby shower themes for little boys, from cowboy- and mustache-themed fetes to parties centered on rubber duckies and afternoons at the ballpark.

A Little Man Mustache Baby Shower
Jessica of Quilted Polka Dot , a mom of two and awesome Etsy shop owner, created this adorable mustache-themed baby shower for a client who wanted a mix of the fun mustache trend with a dash of vintage. By mixing in some hard edges (corrugated cardboard as a table runner, wooden crates) with the softness of ruffles, lace, fabric, and poms, Jessica created a truly unique event.

A Vintage Nautical Shower
If you've ever been on a boat, near the ocean, or just have a thing for seafood, this nautical baby shower is seaworthy perfection . Using the iconic rope-wrapped anchor as a jumping-off point, the vintage-inspired party came together in shades of blue, off-white, and a bit of red. Gorgeous desserts, messages in a bottle, and the cutest crab cookie favors ever are just some of the enviable shower elements.

A Sweet Lullaby-Themed Baby Shower
Lullabies may be designed to send your baby off to dreamland, but this lullaby-themed shower  was anything but sleepy. The party was inspired by a vintage lamb planter the dad-to-be's father gave to his mom the day he was born, along with a Cuban lullaby his mom sang to him when he was a baby. A sleigh-crib dessert table, Cuban desserts, and Vietnamese food (celebrating the parents-to-be's backgrounds), as well as an abundance of clouds, stars, and sweet lambs added to the shower's lullaby appeal.
