Everyone always says that the second child is easier. And, if our baby group is anything to go by, this is often true. But even so, the simple fact that you now have TWO children to look after is enough to push sane people over the edge. You no longer have time to rest--when one's quiet, the other's loud. You'll be lucky to have a half-hour to yourself all day.
I honestly feel like the only way to survive two kids and still retain some semblance of a life and sanity is to have daycare or a nanny. We don't have daycare or a nanny, but I sometimes wish we did so that Jenine could get peace during the day when I work.
