The idea of twins

Our relationship went through so many changes and stages; from long distance dating off and on for years and years (he lived in Canada and I lived in the states) to moving in with each other and renting a vintage apartment complete with clawfoot tub to an industrialized artist loft with two stories, to get married in a court in downtown Chicago. Now, having agreed on a decision to own a house complete with 4 bedrooms, lawn and garage to deciding we should have a child of our own. Both of which happened and finalized within the same hour of each other.
The house was bought and we were wondering if it was too excessive with 4 bedrooms and wondered if we could fill up the one and what we would do with the others. After our HPT's showed positive and our hcg blood test came back positive, we were determined to become adults (finally, in our early to mid 30's). Our first ultrasound showed a little sac and a fuzzy thing in the middle, somewhere in that fuzziness was the combination of our genes. Fast forward to a couple months and our ultrasound was somehow showing two sacs now, which means there were two babies somehow trying to share the same womb. One was confirmed to be two days younger than the other; a naughty egg that decided to sneak in and join the womb made for one. My husband was ecstatic. Me? A whirlwind of panic and denial. How could this be? How were we going to do this? How can we raise two kids when we don't even know how to raise one? It took me a couple months of deciding this will be natural and to accept it before I started to tell anyone (other than my parents).
