Ella or Isabella?

I’m currently 17 week pregnant with my third and last baby who is a GIRL🥰🎀 I’m in love with both the name Ella and Isabella and am having a really hard time deciding between the two. Is Ella an appropriate nickname for Isabella or is it too much of a reach? I would love to be able to name her Isabella but call her Ella as a nickname. Her middle name will be Alice after my grandmother💕 Thoughts ladies?
