S/O os STILL convinced we're having a girl. Yesterday for the announcement prop we made he said we didn't even need to say new brother or sister, just new baby sister. Then tonight at the mall he was singing baby shark to Henry and pointing at each one of us for the different sharks while we left, and he added in sister shark. But not brother shark. I asked him why he skipped brother shark, and he goes " cuz were having a girl." And I asked him how he could be so sure and all he did was go. " It's gonna be a girl, I know it." And I'm like Boiiiiiiii whatchu on though? Being so sure about it.
