When does ANY semblance of energy return?

Just had baby #3 on 9/01, and I swear, I have to DRAG myself to do literally anything. I’m so tired, and I have no motivation to do anything extra (besides immediate baby/child care tasks) I’ve been trying to sleep as much as I can at night, and *sometimes* I can snag a 30 min nap during the day, but I just feel SO. EXHAUSTED. And of course, I only get a few broken hrs of sleep per night, no matter how early I try to get to bed. I don’t want to go anywhere, or see anyone, or deal with any appointments, nothing. But I’ve had to do a bit of everything & I’m TIRED OF FEELING TIRED. I don’t want to let anyone watch baby cause everyone has been sick lately, and my husband is working nights, so it’s not like he can help out all that much, it’s just been rough. Coffee only goes so far 😩
