I agree with PP and would go with Matilda Daisy. I think that Matilda is very cute name for a little girl, but that it can also be sophisticated adult - based off names alone, I would be more likely to go to a doctor named Matilda than one named Daisy. Daisy is a very nice name, but it sounds rather young to me. Also, it you named your LO Matilda Daisy, you would be keeping the trend of giving all of your girls floral middle names.
