K.W.
You are not alone, but you are not abnormal either.
Some of the biggest stealers of memory are:
- stress (your move, parent of young kids, etc.)
- sleep deprivation (you are the mom of a 1-year-old)
- hormonal disruptions (you are the mom of a 1-year-old)
- busy-ness (clearly you have a lot going on, more than the average person since your older child has an autism issue)
Some of this you can't do anything about. Some of it you can!
I made more space in my brain by finding an organizer that actually works for me and writing everything down--dumping all those logistical details out of my head.
I got some sanity back by swallowing my ego and saying YES to opportunities to nap. Keep "the goose" healthy and it will keep "laying golden eggs!"
And don't be fooled by the false economy of multitasking. Brain science shows that we don't actually focus on multiple things at once, no matter how well we think we are. The brain is good at switching quickly from one focus to another, but not at holding a focus on multiple things at once. It's simply not built that way. Studies show that multitasking makes things take longer and they aren't done as well.
Also, I have been forcing myself to make short diary entries just before I fall asleep. You might write things like, "Had lunch with Sheila today. We talked about books and gave each other recommendations. We agreed that I'd read X and she'd read Y and we'd set up another lunch next month to share our opinions."
Finally, remember that you are in a new place, so you will be meeting a lot of new people, yet have less "context" than usual to place them in. Give yourself a break and don't panic!
