Which one is which?

The boys are continuing to grow and keep us on our toes almost 24 hours a day. They are sweet little guys though. Max is in the mid 7 pound range and Matthew is in the mid 6 pound range. I took these pictures the other day and didn't realize how alike the boys look until I looked at the pictures. Max is on the lady bug blanket and Matthew is on the pink one ( I know I know, but I ran out of clean blue ones and I had pink from my girls)
