My mother always had low hemoglobin, it was inherited to me. My hands and feet are often frozen.
I remember trying to warm my legs at night about my mom, and she didn't like it, apparently, and it was cold.
I got married. The husband is always hot. He doesn’t even notice when I warm my limbs around him at night. And my daughter seems to be in him. When she can’t sleep, she complains that she’s hot, turns, I put my hand or even my foot on her. And she says, “Oh, cold, how good,” and falls asleep. I also have a crap :)
