I'm actually struggling with this too. I've been struggling since the baby was born last year. I just am so exhausted I don't wake up in time, or I'm taking care of the baby and have no time at night. I had a shower Saturday and one this morning... last week I don't remember. But I know it's been only 2-3 a week recently.
Also struggling to get clean clothes. Doing laundry has been more than too much. I am right there with you.
