A 38-year-old woman is accused of having a baby daughter with a boy she allegedly sexually abused.
Sarah Campbell is charged with 16 counts of sexual abuse against two boys between 2016 and 2018.
One charge specifies that her daughter was conceived on one of the occasions when she allegedly sexually abused one of the boys.
Campbell appeared at Sefton Magistrates' Court in Merseyside on Wednesday morning before magistrates C Parkinson and A Buxton.
She faced 13 counts of engaging in penetrative activity with a boy aged between 13 and 15, all of which allegedly took place between 2016 and 2018.
Campbell also faces three charges of engaging in non-penetrative activity with a boy aged between 13 and 15 between 2016 and 2017.
Luke Unsworth prosecuted the case on behalf of the Crown and Graeme Halliwell represented Campbell.
A court clerk explained the charges "can't be dealt with in magistrates court and have to proceed to crown court" due to the seriousness of the alleged crimes.
Campbell, of Bootle, was released on conditional bail until her next hearing, which will take place at Liverpool Crown Court on 9 June.
