Big sister having hars time with baby

Yazmin

I have a 3 year old daughter. And a 2 month old baby boy. She love her baby brother but doesnt like him crying. She covers her ears and tell me that his crying and to make him stop. I tried to tell her he needs to cry something because his a baby and doesn't talk like her so i could know what he wants. My baby only crys when his hungry and wet. He always had slept good in the day and night. I need some help on how i can help my daughter out a little.
