There’s no shortage of reasons to throw a swingin’ party — there’s the Oscars, Bachelor viewing, you name it! Singer Pink just topped them all, however, with what is pretty much the best reason for throwing a bash, well, ever.

After recently giving birth to baby boy Jameson Moon Hart, the mommy of one two wanted to make sure her five-year-old daughter Willow still felt super loved and important, so she decided to throw her a “Big Sister Party.”

Complete with an adorable cake that read, “Congrats Big Sis” and plenty of balloons, Willow’s big day was filled with LOTS of love — just look at the grin on that sweet little face!

We absolutely LOVE this idea — what better way to ensure that she feels that Jameson isn’t taking her place as the only child as changes arise in their family dynamic?

It seems to be working thus far — Pink also shared this super sweet snap of the little cutie (who, incidentally, also has pink hair) holding him on New Year’s, and from the looks of things, there’s absolutely no resentment here.

We’ve gotta hand it to you, Pink — this is genius.

Would you throw a big brother or big sis party for your little one? Tell us @BritandCo.
