Tell her she doesnt know what its like being a teen mom, and how hard it's going to be. She probably doesn't have a car or a job or a house of her own, so she's gonna be living off of mommy and daddy (no offence to you younger girls who have to live with your parents)
i have severeal young friends who are moms and they all wish they would have waited.
Shes only been with her guy for a little over a month, she doesn't know waht's going to happen next month or the month after, I hope she waits. Good luck with that.
