Baby cues can be as subtle as a yawn or quiver in their little lips. They can be quick, fleeting, and easy to miss or they can be persistent and unavoidable like crying.
The first two to four weeks seem to be the trickiest, as you are sleep deprived, and healing from birth. As a new mother I believe it took me at least two weeks to distinguish between the baby’s different squeaks, squalls, and cries. However as time passes, you will get to know your baby and be able to predict their needs quickly and efficiently.
