A 15-year-old boy is being prosecuted in connection with the case of a girl who fell pregnant at the age of 11.
The girl is due to give birth next month
The girl from West Lothian - who would become one of the UK's youngest mothers - told a newspaper that she was looking forward to having her child.
The teenage boy is due to appear in court in July charged with rape because of the age of the girl, who is now 12.
The case has prompted calls for a better teenage sexual health strategy in Scotland.
Green MSP Patrick Harvie said it showed that deficiencies in Scottish sex education must be addressed.
The Scottish Sun said the girl, who has not been named, had unprotected sex with the boy on a night out with friends in Edinburgh in August.
She said she was looking forward to motherhood and hopes she has a boy when she gives birth.
The girl added that she thought she would be able to cope as she'd had "lots of practice" looking after young children.
"I'm enjoying being pregnant - even though I get a bit of a sore back and sore ribs."
Her 34-year-old mother told the newspaper: "I'm not ashamed of my daughter at all - in fact, I'm proud of her for keeping her baby."
The newspaper said the girl smokes up to 20 cigarettes a day.
Mr Harvie, co-convenor of the Scottish Parliament's cross-party group on sexual health, said: "I think we need to do away with this notion that sex education is everywhere and that young people have got all the information they need.
"There are a lot of myths out there and sex education is quite patchy in this country.
"The sexual health and relationships strategy from the Scottish Executive - the implementation of that is going on at the moment - needs to lead to much more comprehensive sex education."
The Scottish Conservatives called for society and families to unite to change attitudes towards sex following the news.
Health spokeswoman Nanette Milne MSP said: "This news will have shocked many people and the impact on the lives of the two children, the mum-to-be and her baby must be the first concern.
"I hope that this incident will draw attention to failings that have allowed such a young girl to go on a night out, get drunk, get pregnant, yet seemingly be ignorant about the risks and consequences."
A Catholic Church spokesman criticised "an increasingly promiscuous culture".
A Scottish Executive spokesman did not comment on the case, but said: "We have a programme of sex education in schools.
"It is something that all pupils should be aware of and it stresses the importance of relationships with a family context."
A spokesman for Lothian and Borders Police said the girl's case would be the subject of a child protection review.
West Lothian Council said it was providing support and working with the family to ensure that the child "gets the best possible start".
