List all of the reasons it's wonderful to have two kiddos. Note: If you are trying to avoid a BFP, stay out of this thread!
I'll start: this is the look on Meredith's face when she saw her brother for the first time:
She was so overjoyed to meet him.
She's so nurturing and protecting of him. The way she'll hug him or plant a kiss on his forehead or cheek melts my heart. Now that he's older, they play together, and which in turns keeps them both out of my hair. I still get a lot of "Get him out of my room" and "Mom, Alex messed up my...." but in general they get along pretty well. They also keep each other occupied in the car. Mer will sing to Alex or hand him toys or even reach out and hold his hand if he's fussing while I'm driving. It's so wonderful to watch them grow up together and see the bond that they have.
I had a girl, then a had a boy, so I now I get to shop in all sections of Gymboree. That's a perk. Shopping is always fun.
Oh, and then there are the cynical reasons to have more than one. If you've got more than one, you've got more than one to take care of you in your old age. More kids = better odds of having grandkids. Let's say your first is a slacker and doesn't want to make grandbabies for you to spoil. Well, there's always kid 2.
Am I helping? Are you feeling better yet, NoVA?
