When it comes to raising a baby, there are a lot of big milestones to celebrate. Is anything quite as big and exciting as baby’s first birthday? Of course, it’s a celebration for baby, but it’s also a major celebration for the parents. The first year of parenthood is full of challenges, worry, and sleepless nights, but also excitement, joy, and love. Celebrate how far you’ve come in the last year. Because no matter what the first year has been like, there’s no doubt that it’s been a wild ride.
While there’s a good chance your baby won’t actually remember the party, you will make sweet memories during the celebration. From a smashed cake to playing with balloons to reminiscing about the last 365 days, the first birthday is a big deal.
Whether your little one’s party is set to take place inside or outside, there are a lot of fun themes to explore that will make for some adorable photos. And remember: it’s about celebrating parenthood and your baby’s first birthday. While some of these party ideas lean towards more over-the-top gatherings, use them to spark inspiration as you create the right party for your family.
Below, check out 22 sweet first birthday themes to consider for your little one’s big day.
