An adoptive mother of three children was convicted of child cruelty after forcing her oldest daughter to carry a fourth baby for her, according to reports.

A teen girl underwent a living hell when her adoptive mother forced her to become pregnant through artificial insemination in order to provide the mother with a fourth child, British court documents reveal.

The girl is thought to have miscarried at age 14, but went on to deliver a baby at 16 after repeated attempts to impregnate herself with donor sperm her mother purchased online.

The mother, who is unable to give birth herself due to a health condition, undertook the despicable scheme when she was denied approval to adopt again, a court heard.

She is currently serving a five-year prison sentence for child cruelty, The Guardian reported.

The daughter, identified only as “A” in order to protect her and her child’s identities, “allowed her body to be used by her mother because she loves her” and said she was “not brave enough” to fight back, the court judgment read.

Homeschooled and cut off from contact with her adoptive father, whom the mother divorced, as well as from neighbors, the girl had no friends aside from her two younger adopted siblings.

Over a period of two years, starting at age 14, she underwent the “degrading, humiliating and, on occasions, painful” ordeal in which she was forced to inseminate herself “alone in her bedroom, using syringes of semen and douches prepared by the mother.”

“A” was compelled by her mother to use douches consisting of vinegar, lemon and lime juices because her mother believed this would result in a female baby.

The girl said she was “shocked, pretty shocked,” by her mother’s sick request, but went through with it, believing “if I do this…maybe she will love me more.” She was also influenced by “feelings of gratitude for [her own] adoption.”

Social services came knocking at the home on four separate occasions, but the “highly articulate” mother was able to mislead them.

Finally, authorities successfully intervened after “A” gave birth, when midwives alerted them to odd behavior from the “pushy and insensitive” mother, and “A’s” reluctance to hand the baby to her.

The judge presiding over the case expressed “an abiding sense of disbelief that a parent could behave in such a wicked and selfish way towards a vulnerable child,” the court judgment read.

Social service agencies are now reviewing the entire case to determine how it could have been allowed to occur, The Guardian reported.
