I've only read a few pages but here's what I would do. Have her and him carry around a 5lb bag of flour as the "baby" for a month. Not the real thing( don't know how you would do night feeding with a bag of flour) but they'll feel some of the commitment's it takes to raise a child. Oh yeah they did this in high school for a class. This makes me nervous having two girls myself. Good luck and I've read some great advice
