Lucky you! You’re planning your baby’s first birthday and it’s summertime. That means that there’s a long list of summer birthday party themes that are as fun and as easy-breezy as the season itself. From watermelon and ice pop themes to hosting an under the sea bash, we’ve got a list of summer party ideas that’ll leave your newly minted one-year-old showing off a sunny, cake-covered grin.

Underwater Fiesta

Your Lil' Squirt will flip for this under the sea party theme. Incorporating shades of blue and aqua with bold pops of chartreuse makes the party cohesive and bright. Our favorite part is that the lunches were labeled "fish food" and that the dessert table cost less than $40 to put together. Visit Celebrations at Home for all the sea-worthy details.
