Ivy's first name is Madeline with a long i, but we are calling her Ivy and expect everyone else to do the same. Madeline has always been one of my favorite names, but we avoided it because it is one of those names that people pronounce 2 ways. Madeline is also a little bit of a big name for a baby or child and since there is already a Maddy in the family we wouldn't shorten it that way. This is why she has the name Ivy. Ivy is a name that seems a bit young for a professional or an adult and it didn't have any good long names for us to take it from. That is why she has the name Madeline. Mija, her acronym, is Spanish slang for mi hija. It is a term of endearment meaning my daughter.
