I'm another mom who has moved past the two under two place. They are 14 months apart and while it was hard at first it's a lot of fun now as they are so close and have so much fun together. I love first thing in the morning. Each one sleeps on one side of me, and whichever one wakes first always leans over to the other with a smile to wake the other for a day of mayhem. The first few months really are all about survival, but once they get a little older you have a little more time to yourself as they entertain each other.
Babyproof- if not everything, at least have one area that is truly stress free. For us, these areas are our living room, our bedroom, and the long hallway between the two. You can relax more when you don't have to worry that they might be getting into something they shouldn't.
I love seeing how close they are, and how they always think of the other.
I made some cookies last week. My older child wandered over, and I offered him half a cookie. He took that half, then reached for the other half as well. Before I could say anything, he presented it to his younger brother saying, "Share." They sat together on the floor smiling and nodding at each other as they enjoyed their cookies as I watched and realized that for them, there really is no line between friendship and brotherhood.
