Duff opened up to PEOPLE last December about why she chose to keep her baby's sex unknown until the child's arrival.

"We had a gender reveal with Banks and it was such a fun memory," she said at the time. "Unfortunately, during these times we felt it wasn't really appropriate. The way we are creating some excitement within the family is to wait to find out the sex on the baby's birthday!"
