Do you think they are identical?

I have been wondering so much if they are identical. They are Di Di twin girls so no help there but they looked so much alike when they were born we couldn't tell them apart. Now we can but sometimes I have to double check to see who is who. I think I will get a DNA test soon just to know. The pic where they are sleeping is the day they came home and the Halloween one is 2 months old. What do you all think?
