I am finishing my first year of Masters and have always thought of going for a PhD in North America. I and my girlfriend are going to have a baby which is totally unexpected. The due day will be somewhere this december which I am still half year away from finishing my Masters degree. 

I don't know under this circumstance should I still, or am I able to, apply for PhD positions overseas. This would mean I will have to leave them or bringing them together for my study. I am not super rich to afford a family personally and would need to rely on studentships, but I don't think graduate studentships are sufficient to afford the living expense and future education fees of my coming baby.

Taking on a PhD and a research career are definitely my dream and situation seems very difficult for these to come true. Anyone knowing someone carrying kids along grad school, or any suggestion to me? I just don't have a clue how to take care of everything.
