Hey girlies. I was just reading on this as I was in this situation. To be honest everyone feels differently about this at every stage in life. Let me just give you my personal experience. I am going to be 24 next week, however I had my daughter when I was 15 and "in love". Now, unlike most people, I will not tell you that you can't be in love at that age. To this day I will say I loved my daughter's father with my whole heart and would have married him had he been good husband/father material. At the time I believed he was. I gave our daughter his last name. We were very on and off through the whole pregnancy and after her birth because he could not stay faithful nor did he want to accept what becoming a parent should mean. I am now married to someone else and we have a son together. My daughter lives with us and has had some issues with the fact that she is the only one of us with a different last name. She is too afraid to allow me to try to change it because what little she sees of her father, has her worried that he would stop loving her all together if she dared get rid of his last name. Blah blah blah long story short. It can't hurt a single thing to give your little one, your last name and then change it when you get married and change yours. That way IF for whatever reason things don't work out, you and your baby will have the same last name which is just another connection on top of everything else. I know that the father is always the father but many don't deserve the honor of their child carrying their last name. Sometimes that is a thing we find out after it's too late. Don't just take my word for it, look around you. Watch Teen Mom or 16 & Pregnant and see how many of those poor kids dads are actually there for them or deserve that honor as I said, of passing on their last name. It's not just a name sometimes. For those of you having boys, it will be the last name of your grandchildren as well, and for those having girls, it will be the name she carries until she gets married and even then she may choose to stay with her maiden name. Think about if that boy were to walk out on you 2, would you rather honor him, or yourself? Love to you all and I hope you all think it through before you decide. NO MATTER what you decide though, congrats to you all! There isn't a wrong choice really, just what is more comfortable for each person.
