I completely agree. I had mine at 21. By the time I was 40, active parenting was done and dusted. I had all that travel, childfree holidays and stuff in my 40s with the added bonus of much more money to enjoy it than I’d have had in my 20s. I have zero regrets.
Being able to do all those things in your 40s does sound great, but you have to juggle it with work and other general life-related responsibilities (servicing a mortgage, home, etc). And then it’s just you and your DH, or you and a group of girlfriend going on the odd holiday here and there.
I did all that in my 20s, when I was surrounded by other carefree, responsibility-free 20-somethings, and it was a fun, whirlwind decade of seeing the world, making friends, flatting, going out and having good times.
I then got with DH on the eve of turning 30.
I definitely think there are pros and cons to both having kids early, and doing it later.
But, for me, it essentially comes down to being with the right man - someone you love and like, who has your back, and enables you both to be in a good place to raise your DC to the best of your joint abilities.
And that’s something that doesn’t happen within a set time period.
