On Tuesday, the father, also 14, was placed on one-year supervised probation by the Juvenile Court, after he pleaded guilty to two counts of carnal connection.

The teenager could have been jailed for up to five years and fined up to $10,000 for each charge if he had been 16 when he engaged in the acts.

He was also ordered to stay indoors from 9pm to 6am during the probation period and will have to perform 120 hours of community service.

The baby has been put up for adoption. The two teens met in July 2007 through the Internet when they were both 13. They were initially 'casual friends' before getting serious a month later.

The girl started visiting his flat and they had sex there for the first time. The young couple also had sex sometime in December 2007 at the boy's place.

It was only in July last year that the girl suspected she might be expecting after missing her period for several months.

It was also around this time that her parents confronted her. The girl denied it initially but a subsequent check-up showed that she was 28 weeks pregnant.

The 15-year-old joins a growing group of girls in Singapore who are having sex under the age of 16. Last year, 310 teens were caught engaging in consensual sex - nearly 45 per cent more than 2007.
