I feel (and think) that, the dad!, can be as nurturing as the mom. I'm a dad of 3 kids. A 12 year old girl (from 1 marriage) and 7 & 5 year old boys (from my current marriage that is soon to be over). It definitely changes when it is your own kids. I was 37 when my daughter was born and being older helps me be a better parent because I have more patience and many other traits older adults usually have over younger adults that help them be better parents (except energy).
Also, I honestly believe being transgendered helps me be a much better parent. I have such a higher nurturing instinct that a 'normal' guy does. I have the boys full-time and have had them full-time since before Christmas. I may have them full-time for the rest of their childhood. It's complicated. But, they are NOT lacking in any nurturing aspects and they have always been just as likely to call out for dad in the middle of the night when they had a bad dream than call out for mother. Actually, they'd usually call out for Dad because Mom was a heavier sleeper and I would wake up faster when they called. To say women are better nurturers or that men are better is sort of a sexist thing. In reality it depends a great deal on the specific parents involved.
Would I have a kid if I could become pregnant? Not anymore, I'm 49, almost 50 and too old to have more kids. My original retirement plans had to be modified because if I retired when I had planned I'd still have 14 and 16 year old sons in the house. Nope, gonna back my retirement up by about five to ten years. We'll have to see how they are with college.
