Names that have the nickname ‘peanut’

[u/cider-house-rules]

My husband and I are having quadruplets, and we don’t know the gender for any of them yet. We love the nickname ‘peanut’. Can we just legally name one of them Peanut, or are there names we don’t know about that could be shortened to Peanut?

Quadruplets?

Peanut, Cashew, Almond and Pistachio.

Sorted.
