What does it mean to dream about baby poop?

A constipated baby needs an adult to provide help to move what needs to be moved, that is, eliminated. The baby may represent yourself, suggesting that you need to "push" yourself to get rid of stuff you don't need anymore - stuff that will cause very big trouble indeed if you don't move it out. Or, the baby might represent something else, such as a project, that needs your help to get things moving.
