Boy and girl names

Bb • Wife and mother of two children, 👼🏾 baby April 2017, 🌈👶🏾 due September 2018

We were unable to find out the sex, I’m absolutely rubbish when it comes to thinking of names, I have two children already one named Tahran and the other Shaniah

Anyone have any ideas for either a boy or girl to go with these two names?
