It's been almost a week now since the new baby came home and so far it hasn't been so bad... in the same way that getting punched in the face isn't so bad when you consider it could have been a kick in the nuts.
Mac is sleeping a little better than Sam did when she came home, as is evidenced by the fact that I'm writing this now instead of laying on the couch with a caffeine drip, which is how I spent the first week of Sam's arrival. Of course, when Sam came home she was the only baby in the house so on the rare occasion when she did decide to sleep a little, I could sleep too. Now, I can only sleep when Mac is asleep and Sam is asleep which, according to my calculations, should occur sometime around Easter.
Sam is mostly indifferent to the new baby, although she does get upset if Mac starts crying. Yesterday I was holding Mac as she cried and Sam came over and put her head on my leg and started crying, too. It was so sad to be the cause of two girls in tears. I haven't felt that way since I had a threesome in college.
