We thought of the unfolding fern buds, or korus, as they symbolize a new growing life, and life continuing in our children when designed with a smaller koru growing from a bigger one.
Mirroring two of such fronds we got a heart, a symbol of love, where the two parents ideally embrace the two newborn babies.
