It doesn't sound like you have much experience being the 24-hr care provider for a baby. Phoning it in at work is way more relaxing than being in the house with a baby for the entire day. It's not work that makes parents need to sleep, it's... needing to sleep. Just speaking from experience, having someone with fractured mental concentration cooking, attempting to keep a slightly mobile child from danger, trying not to fall asleep on the couch with the kid in a desperate attempt not to cosleep, trying to keep your cool as the kid screams again and can't be soothed.... much more dangerous and stressful than doodling thru a meeting and saying, "I'm sorry, can you repeat that? I just want to clarify what you're saying."
