Based on skull theory? 💙 or 💜?

Emmy • Mon, Jul 03 • Momma to two little beauties. 💜 Healing from loss. 👼 Rainbow baby due in September. 🌈

I can't figure out this skull theory business. When I think I have it figured out for someone else's ultrasound picture I look at the comments and they're opposite! 5 weeks until I get to find out 😍
