A MOTHER has confessed to drowning her 15-month-old daughter in the English Channel because she was "incompatible" with her love life.

Fabienne Kabou faces life in prison after authorities traced DNA on the toddler's pram to the 36-year-old woman, who lives in Paris with a 63-year-old man.

Little Adelaide was found dead on November 20 by a fisherman, strapped in her pram and submerged in water in the English Channel, reports the Mail Online.

A day earlier, CCTV footage captured Kabou, 36, pushing Adelaide in the same pram to the coast of Berck sur Mer, in northern France.

After a 10-day search, police located Kabou, a native to Senegal, who told authorities she felt motherhood was "incompatible" with her love life to Adelaide's father.

The father, a sculptor, was told Adelaide was in her grandmother's care after agreeing to look after her back home in Senegal.

On Saturday, Kabou was detained and questioned by authorities under police guard in Boulogne, where her lawyer, Fabienne Roy-Nansion, said her client made a full confession.

Adelaide's father told French newspaper Le Parisian Kabou was "a magnificent" mother but locals are not convinced, as hundreds protested outside the court in a White March against child cruelty.

"She is not crazy. Her actions were premeditated," said Gerard Lopez, the president of the Institute of Victimology and legal expert at the Paris Court of Appeal.

"By getting rid of the child, she may have been trying to meet the needs of her boyfriend who wanted more attention."
