Aww what you said is very sweet. I don't have kids yet, but surely I want to have them someday.
What you say about the biological clocks sometimes worries me, because I'm a medical student and as you maybe know this career is pretty long, and sometimes I just think if I'll have the time to have children before it's too late. Because I don't want to have them now, I'm so young and I don't even have a job, and I would like to end my career first because the schedule is very heavy and I wouldn't have the time to raise a child while studying.
