Seriously, everybody - his girlfriend isn't being just a little nervous. She is suffering from a serious postpartum anxiety disorder that often overlaps with postpartum depression. She needs medical treatment!!! Please stop minimizing it. Here's just an excerpt from an article on it:
"Everyone experiences anxiety differently.
But people with postpartum anxiety experience thoughts that are usually:
uncontrollable racing consuming disrupting overwhelming recurrent irrational (not logical or realistic) frightening
These uncontrollable, consuming thoughts tend to center on a few major areas of worry, such as:
fears about the baby’s and one’s own health fears about a parent or partner becoming ill or dying a sense that something bad will happen irrational obsessions or fears blaming oneself excessively when something goes wrong or feeling excessively guilty
Postpartum anxiety can also cause physical symptoms, including:
unexplained exhaustion trouble sleeping trouble concentrating increased irritability muscle tension feeling on-edge, restless, or wound-up a rapid heartbeat feeling panicky for no clear reason
Postpartum anxiety may make it harder for a person to bond with their baby. It may also negatively impact a baby’s mental and physical development. Left untreated, postpartum anxiety can also lead to serious negative consequences such as infant neglect and, in extreme cases, infant death. "
