...is having more than one!
I meant to post this before daughter Berkeley Celeste was born, since it was the main thing I was worrying about, but time drifted by so quickly and the next thing we knew, she was born.
But the big "inconvenience" has to be the dilemma of what to do with your other kids while your current kid is being born. When Jackson was born, our firstborn, Nolan, had to endure all day babysitting until I could make it back from the hospital to pick him up. He actually went through two sitters that day, one whom he didn't even really know that well. And to top it off, he didn't get a nap because he was completely out of his element. Oh the humanity!
This time we had two kids 3 and under to find places for. Thank God Berkeley was born under cover of night so I could put both boys down to bed, giving us just (barely) enough time to call in some nearby and parental (2 hours away) reinforcements while we rushed off to the hospital. She was born before midnight, so I was able to return home before the boys woke at 6 a.m. Then I fed them, dressed them, and sent them off to school. They were none the wiser until I brought them to the hospital to meet their baby sister that afternoon.
So really, it turned out not to be as inconvenient as I thought it would. In fact, it was quite convenient. But the lead-up was all worries nonetheless.
