A fussy baby can cause great anxiety for a new mother. She knows that her baby is upset and uncomfortable, but is unable to calm her baby. If her baby continues to cry on a long-term basis, she begins to rationalize that she is the problem. Her self-esteem decreases and she begins to doubt her ability to parent. What many new mothers do not realize is that her fussy baby may be reacting quite negatively to something that she is eating. By simply changing her diet on a short-term basis, a new mother can calm her fussy baby dramatically.
