I don't think one can regret having a child as there's too strong love for a child. But in a way, if I knew how bad it would get, I would rather not have a second child. I was having mild symptoms of bipolar, but it never got really bad and out of control, so I had not even seeked medical help before I had my second child. They are only 2 years apart and having that small spacing was hell. In total I had 6 years of disturbed sleep as the youngest kept waking up at nights untill 4. I have been stable only after that. In my heart I want a third child, but now way I'm going for it, I'm scared. One of my friends with schizophrenia has gone off meds to try for baby and she gone from long term stable to total crap, so I'm scared.
Sorry for being so negative
