Teenagers in high risk demographics already know what sort of hassle having a baby is because of the example of peers or family members or neighbors. What they're much less familiar with is what they'd be giving up (ie all the life opportunities that they lack the experience to model as available options), and this naive discounting of the future distorts their risk calculus. Rather than working to increase their weighting of the known-negative outcome by saddling them with $700 Tamagotchis, it would probably be more effective to reduce the actual risk with greater focus on contraceptive methods etc.
(Similarly, very few people plan to fail, but lots of people fail to plan.)
