The correct answer is B. Tell Diane's medical caregiver that he thinks Diane is suffering from postpartum depression
Explanation:
After giving birth, it is common some women suffer from postpartum depression. This depression occurs due to the drop in hormones after giving birth and difficulties in fitting in a new role as a mother. The symptoms of this depression include anxiety, excessive crying, loss of appetite, mood swings, irritability or negative thoughts towards the baby and even suicidal thoughts. Additionally, this depression should be treated as soon as possible to avoid negative consequences or long-lasting depression.
According to this, it is likely Diane is experiencing postpartum depression as she shows some of the symptoms of this depression such as mood swings, irritability, and suicidal thoughts. Because of this, she must receive medical attention and therefore Rick should tell Diane's medical caregiver that he thinks his wife is suffering from postpartum depression.
