Creating a theme from scratch can be as simple as selecting fun paper and rubber stamps. Martha used bandanna and dot patterns to create a festive celebration that's perfect for children of all ages.

The big idea here is that it's a small world after all. At this charming party, girls will feel like Alice after she goes tumbling down the rabbit hole.

What little girl doesn't have a soft spot for polka dots? They're colorful and playful -- and most of all, they're fun! With that in mind, celebrate a birthday by having everyone see spots.

For this party, clear out a room, fill it with orbs of all sizes, and let toddlers at 'em. You can also decorate a cake with a bouncing-ball icing pattern.

What's a bash without a few party animals? Select your child's favorite -- we monkeyed around.

Surround your birthday girl in her all-time favorite color (of the moment).

Invite a gaggle of girls (or boys) to celebrate silliness at your child's next birthday.

It's as easy as ABC to plan a party using the initial of the birthday child.

What do you get when you combine pajamas, facials, manicures, and fun? The perfect menu for a spa-themed sleepover birthday party.

Make the season when the birthday child was born the theme for a party, and mimic nature's decorations -- snowflakes for a party in winter, flowers for summer, and even insects for a spring party.

Preschoolers have a knack for getting dirty -- so why fight it? Instead, make it the theme of your little one's birthday party!

Host an Old West-themed birthday party, complete with cactus cutouts and a Gold Rush game.
