　　It's common for new mothers to experience depression (抑郁) because of hormonal changes and lack of sleep after childbirth.But new research shows that depression after the arrival of a child isn't limited to birth parents：adoptive (收养的) parents are also at risk of depression after bringing a child home.

　　Depression appears to be common among the two million couples in the United States who adopt children every year.A study of 39 adoptive mothers showed 15 percent were experiencing depression six weeks after the adoption.25 percent of parents had experienced depression before the child had arrived，which can be explained by the uncertainty and hopes that are common during the adoption process.

　　To find out more about what causes the adoptive parents to experience depression，a Purdue University professor，Karen J．Foli，who is also an adoptive parent，interviewed 21 parents who had adopted children from newborn to 12 years.

　　The research found that the depression experienced by adoptive parents often stemmed from unmet or unrealistic expectations of the parenting experience.During the adoption process，parents put lots of efforts into proving they will be nice parents.After the adoption，some struggle with the fact that they aren't the "superparents" they promised to be，Dr Foli said.

　　Adoptive parents also must cope with family members who don't treat a new adopted child the same way they treat other biological children in the family.

　　In addition，while birth parents often spend their time together as a couple and pay close attention to the mother's health，adoptive parents have to do a large amount of scrutiny (审查)，paperwork and travel.Often，Dr Foli explained，they are simply tired by the time the child arrives.
