Attachment methods of twins?

I’m learning about attachment methods with infants and mothers, but it got me thinking about twins. Do twins have attachment types between them and if they are not attuned to each other can this cause similar issues to a mismatched mom and infant? I was thinking about something my mom told me about my twin and I. She said I was always attached to him, but he couldn’t care less if I was around or if I wanted to play (from when we were infants).
