There’s no way Usagi in any incarnation would ever stop celebrating her own birthday. Even if it means sneaking into the crystal kitchens multiple times a day for her requisite intake of cake. Just enough for her to maintain her usual elegance.
Chibiusa sees her mother’s royal composure and half of her mind is like “I want to be a lady like my mom, and I suppose a lady must retain her humility and never seek such attentions” and the other half is like “GOD DAMN IT I JUST WANT A BALLOON AND A CUPCAKE MAYBE EVEN JUST LIKE A PAT ON THE HEAD AT THIS POINT”
