Postpartum Laziness

I delivered my 2nd a little under 3 weeks ago & I have so much to do. I still haven’t finished unpacking, laundry is piling up, dishes need washing. I feel like I’ve recovered well enough to do simple tasks but I just have no energy. All I do is lay around with my little one. I barely want to change a diaper. With my first I was pretty much back to normal the second week. This pregnancy & labor took so much out of me.

Did anyone experience such extreme inability to complete simple tasks? How can I increase my energy/motivation?
