The first week of paternity leave went pretty well. Tuesday was super easy, all playing and napping and casually eating. This made me overconfident. Wednesday he had an upset stomach and was really, really crabby. This made things much more difficult, and I was pretty sure I was doing a terrible job and he hated me. Thursday and Friday he felt better, and we finally started getting a routine down. As the week progressed I also started getting more competent with the bathing/changing/feeding/etc, so he was better able to put up with my ministrations.
