Nickname for Mathilda

Britany

I love my daughters name so much, but nobody calls her by her full name because its such a mouthful. What are some good short versions or nicknames that you know of? I absolutely hate Mattie for her, and that’s the one most people default to. It just doesn’t suit her at all so it drives me crazy (the name mattie is fine! Just dont like it for her). She is eight months old now and I am seriously considering changing her name because I don’t want people to call her Mattie. Help!
