-you call them "the babies" and they are not twins.
-they can share pacifiers.
-they can share diapers.
-the babies have to wait in line to get their diaper changed.
-they can share sippy cups.
-you have not had a good night's sleep in almost 3 years....4 1/2 if you count pregnancy.
-you do the math to make sure they are not going to be in the same grade.
-you foresee breaking them of the paci at the same time.
-you are able to buy the same car seat for the younger one that you bought for the older one because the store still sells the same make and model....in the same color.
-you never stopped using the diaper bag between children.
-the maternity clothes were still hanging in the closet.
-you are confident they will be able to share a car when they turn 16.
-you get to laugh at children walking like drunken sailors one right after another.
-you get to hold another brand new baby in your arms sooner when they are close together.
-about the time one kid grows out of the cute toddler talk...you have another one to replace it.
-you get to see the wonder of the christmas tree lights with two little ones at the same time.
-you get to watch them dance together.
-you have two children that will sing and dance with you at the same time. instead of one that thinks you're cool and another that has outgrown your silly shenanigans.
-you can use baby food you didn't use the first time around...but kept just in case. i'm kidding...
it's hard work, i'm exhausted most of the time. but my goodness, these babies are a lot of fun!
