To my best knowledge, your mother and I are both back-sleepers, but since your mother’s pregnancy she’s been sleeping on her left side because it supposedly increases the amount of blood and nutrients to you.
This has been a source of discomfort for her because sleeping on that left shoulder leaves her with a sore arm. She’s tried a body pillow, stacking the head pillow to elevate her shoulder, and even rotating her entire self ninety degrees to get propped up by the headboard (luckily she’s short enough / our mattress is big enough so that she fits the length and width of the bed). Unfortunately, nothing’s really worked. She often fantasizes about Lucy Knisley’s ingenious Moat Bed (someone Kickstart this please).
You’re also cramping her bladder space, so she has to get up once or twice in the middle of the night to pee, at which point she’ll observe and report to me that I was actually sleeping on my side! Shocking. I believe she’s heard me mumble random phrases. I hope I don’t ever say anything stupid. There’s no defending or denying something in your subconscious.
However, one benefit to sleeping on her side is obviously the back scratches. For my ease, I have your mother sleep an arm’s length away so I can move my entire arm rather than my elbow joint, which gets sore after thirty seconds or so. Thirty seconds is considered a warm-up scratch.
In other sleep-related news, our bed conversations have devolved in recent days. Last night, the topic du jour was how to jiggle each other’s butt. I thought it was a pretty straightforward process. Your mother, on the other hand, went with a descriptive analogy of bouncing a basketball that’s resting on the ground: “light repetitive tapping to get it going.” She continues, “Sometimes you need an extra sudden force to start such as a hard slap on the ball.” And in your mother’s case, she’ll punch the ball with a fist to generate the necessary force. I turned away your mother’s attempts to demonstrate. After a bit too much laughing, she put herself on a self-imposed timeout and we promptly fell asleep.
