What are some signs that my bub is overtired but just can’t seem to sleep.

The biggest reason babies won’t sleep is that they are overstimulated and overtired. Signs that your babe is overtired are having a fixed-focused spaced-out stare; flailing arms, kicking legs; second and subsequent yawns, short wailing cries with short breaths in between, escalating to long, hard, red-in-the-face crying; baby seem angry; turning away from light or people; losing eye contact; jitteriness of the lower jaw; squirming when picked up and turning in towards your body, rubbing their eyes or cheeks or pulling their ears or scratching their face.
