I went through this too a lesser degree when I was pregnant with The Toddler. Back then it was mostly just a reading slump, since I was working and hibernating wasn't an option. The reading slump was...Extensive. The only things I wanted to read were The Cat Who... books, Spiderwick, and Redwall, and that is literally all I read for over two years. TWO YEARS.
This time I'm in full on hibernation mode and I can feel the slump coming. I'm 200 pages in to A Court of Wings and Ruin by Sarah J. Maas and I just can't seem to get into it but I picked up The Cat Who Robbed a Bank and I can't seem to put it down. I'm avoiding leaving the house unless it involves a drive-thru or a bookstore, even though we just bought a new (to us) car so that I'm not stuck at home all day. It's like I just want to be home, and be comfortable, and cozy, and not have to deal with people.
I don't know is pregnancy hibernation is actually a thing or not, but it's pretty real for me. We've had someone at our house almost constantly since we moved in, it seems, and I'm to the point where I just can't stand it anymore. I want to be alone and not have anyone here for anything for like a week, I need some recharging time and I need it fast. But I've also got some reading goals to achieve this year and I do not want another two year reading slump. I need a plan to keep myself from falling into that 'comfort reading' thing that led to the slump last time.
So the plan is as follows, and I'm making this up as I go along so bear with me;
1. Stay home - No leaving the house except grocery shopping and doctors appointments.
2. Read the 'comfort reading books' - That's right. I'm going to read them.
3. Limit the 'comfort reading' - I can easily read one Cat Who... book a day. I can read 3 Cat Who books, then I have to read one other book.
My reading will be slow for a while, and interspersed with lots of Cat Who books. I've read the whole series more times than I can count, and I will probably read them 2-3 times in the next few months but I'm okay with that. So that's the plan for now! Happy reading!
