Mother has told me that I outta be a pro at this twin thing by now, since I've had more than 30 years of practice.  I will say being Momma is a bit different than the big sister though.  There are some things that are familiar, the endless comments, the double looks.  And of course the craziness, but then again, in a family of four kids, there has always been some craziness, what is two more in the mix?  I'm sure there will be a lot of things that will be more difficult in having two the same age at once, but we are looking forward to the two new little ones in our family.
