Why do I have no energy at all after birth

Usually it's lack of sleep, a round-the-clock load and your body readjusting. It isn't laziness or a weak character.

In periods like this, “pulling yourself together” works worse than lowering the bar: a short session instead of a full one, a breathing practice instead of a workout, sleep at the first opportunity.

The Mindfulness section has practices for recovery and sleep, and Nutrition shows whether your food is slipping — that's often part of the energy story too.
