I will start with the disclaimer that all of our’s were conceived naturally, but that aside, here is my experience:
DC1 born when I was 25 and DH was 41
DC2 born when I was 26 and DH was 42
DC3 born when I was 33 and DH was 48
DC4 born when I was 35 and DH was 51
While I have felt the effects of being older in my subsequent children’s childhoods (partially due to suffering horrendously during pregnancy), DH has actually improved in his abilities and vigour as a parent.
DC1 is 18 now, DC4 is 9, I am 44 and DH is 59. I actually think DH has more energy for the kids, physically (although that may be partially due to the fact that I often work 60-80hr weeks and DH works pretty standard 35-40hr weeks, I work shifts, so we are lucky to still be able to be there almost all out of school hours for them all, apart from DC1 who is at uni, still lives at home, but spends a large amount of time out of the house).
I got cancer at 35 when my DC4 was still a baby, which I almost didn’t survive, DH is still fighting fit. Thankfully we are both now well, capable and involved parents.
So really, all those words were to show that, most people wouldn’t bat an eyelid at a female becoming a mother at 35, and would have quite strong negative opinions about a male becoming a father at 51, however my experience just goes to show that, extremes aside, age can’t really predict health, or how your journey as a parent will go due to it.
Follow your heart OP, be prepared for the good and the bad, and good luck ❤️
