Perfect ‘birthing age’(for both parents) is 17 - 23, IMO.
I’m in my mid 30s myself, and have some small children. When I was 20, I was VERY MUCH more able to keep up with them. lol It doesn’t seem to phase my wife any. She could probably have 6 more, keep her 115lb body weight, and run after them just as she did when she was 19. She’s like a machine. lol
You are probably right, both in terms of the health of the child and its relationship with both parents.
20-25 IMO for women and add 5 more for men. Get them over with!
But, 22 biologically, for women I remember reading. Let’s not forget that at 47 the odds that the child will have problems (downs for one) are way up there,
