I am currently 6mths pregnant and have a 9mth old little girl and their father just walked out on me about three weeks ago. the only time he sees our 9mth old is when i drop her off to him for me to go to work. if i didnt drop her off i dont think he would even make an effort to come see her. He has only went to one dr. app. while i have been pregnant with our second child. What should i do? Should i file for full custody of both of our children? we are not married and our 9mth old has his last name... Should I give our next child my last name or his?
