We intentionally celebrated both of our kids first birthdays without guests other than one grandma, but we treated everything else as if it were a party. Tablecloths, banners, balloons, smash cake, big cake, punch in one of those fancy beverage dispensers, themey toddler outfit, etc. This way, the pictures imply a party and WE feel like we had a party even though we didn’t. Our other favorite detail though, was that we invited all grandparents and aunts/uncles to attend the party digitally, so we FaceTimed everyone on different devices (no Zoom at the time! ) and set the devices up so they could see the birthday kid! (With our first, I even mailed party favor treat bags to “attending” family members so they could eat treats while watching our son eat cake. Bailed on that for #2. ) Anyway, we didn’t want to take up their whole day, so we greeted them, sang happy birthday, opened presents, and then let the birthday child smash their cake. Then we said goodbye to the digital family members before bath time. Worked shockingly well! Best wishes and happy birthday to your little one!
