I get it. I did it. I loved it. I was meant to be a mom and loved every single second of being a mom. I could not have loved my kids more if I tried, they were everything and then some. Were they perfect angels? No. Was there some heartbreak in there? Of course.
But I loved being a young mom. It was what I wanted as my own mom was considered 'elderly' at 36, when she had me. And I was fortunate to have had several years of marriage before we decided to start our family. My H could have gone either way on the subject because he liked having all my attention all the time before the kids. But he loved our kids once they came. Had he been more indifferent it might have never happened, but he knew it was the right thing for us at the time, so he did not hesitate.
I had my first at 23.
Was it hard? Yes. Were they expensive? Duh. Was it the happiest time in my life, bar everything else? Absolutely. Is it rational in this day & age to want this? Probably not, but I would wish it on everyone, it was the most joy I ever experienced in life. I can only hope that they realize how much they were cherished as children, and can be loving parents themselves one day.
