Parenting Sleep On The Floor
- Chris describes dozing off on his one-year-old's floor while the child pokes his eye with a thumb.
- He uses this story to illustrate chronic tiredness from parenting and interrupted sleep.
Sleep Isn't Necessarily One Solid Block
- Russell Foster explains human sleep historically was biphasic or polyphasic, not a single uninterrupted block.
- This reframes middle-of-the-night waking as normal rather than a failure requiring panic.
Calmly Manage Night Waking

- Try leaving the bed, listening to music or reading a few pages until you feel sleepy and return to sleep.
