A family court judge has ruled a baby whose father lives in a "complicated" relationship with two women should be put up for adoption.
Judge Sarah Lynch was told the man was living with the little boy's mother and "another woman".
A psychologist who assessed the family said the relationship was "not good" for a child.
The relationship was one of a number of concerns raised by council social workers with welfare responsibility for the youngster.
They also said the baby – who is a few months old – was living in a flat which was "unhygienic and inappropriate".
The baby's parents had agreed they could not bring up their son.
Judge Lynch concluded the baby should be placed for adoption – saying his parents could not meet his needs.
"The psychologist felt there were a lot of complicated things in the relationship between the three grown-ups which would not be good for a child," said the judge.
"Overall, she said she would have a lot of worries about the parents' ability to meet (the baby's) needs either together or separately."
She added: "Father... says he knows he cannot give (his son) what he would need from a parent. Mother too says that she thinks it would be best for (the baby) if he was adopted."
The judge, who is based in Leeds, has outlined her decision in a written ruling following a private family court hearing.
She said the little boy could not be identified.
Judge Lynch said the man had an older child born following a relationship with a third woman.
That child had also been taken from his care in the wake of an earlier ruling by a different family court judge.
Judge Lynch said in that case social workers had also raised a number of concerns.
One concern included the fact the child had been fed ice cream when "only" 15 weeks old.
