For this party theme, think about using teal, pink and purple colors and bust out your bubble machine, seriously, babies love bubbles. This theme is also an ideal choice for a pool party.

Use lots of shell and coral accent items and feel free to go full-mermaid with everything from your decorations to your sweets. I mean, just check out how adorable these handmade custom cookies are?!

Or how about a more Southwest style with tribal prints and Mexican blankets? For a more natural take on this theme, try a cacti oasis with desert plants like succulents to tie into the decor.
