every parents nightmare, thats a tough call, it all comes down to her goals, and your ammount of help. if you feel that you wuld help with babysitting, and her completing college is a must, then keeping the baby is an option, but when the day is done its her life, 19 is one year old enough to make your own decisions, and if your mature enough to have sex and make a baby, then you have to reap what you soe, personally when i was her age, me andmy stead girlfriend were really careful, antibiotics can mess with hormone birthcontrol, missed doses and so forth, and there is always the chance that with all modern science, you mess it up, if i was 19 i would do the unpopulat thing, but she is in her 2nd trimester, and window for termination is closing fast, adoption is a tough one, being she is able to take care of the kid, and the thoughts of a profitable life vs the mabe not so profitable life, or not so easy profitable life, thats not enough in my mind to turnmy baby over to someone else, i am the most open minded person you will meet, and weigh all options, but the biggest thing here is that time that she waited to tell, and to start making decisions, sounds like the family needs to have a sit down TONIGHT and talk numbers, involvement, and tough choices, and then you neet to see a doctor monday, cause either way, the mother needs to be checked out to ensue that everything is ok, and, if the decision is to make the tough call, and do what no one wants to do, but sometimes must, then the doctor can help you also, thats how i see it, good luck
