I was reading this blog I just discovered (which I just love) about this young mom of two boys. She's 25 years old and has two kids. I thought: I wish I would have had two kids when I was just 25! And then I thought aloud: Kyle, why did we wait to have kids? I mean. . . I know why (worldly thinking). . . but I wish we wouldn't have.
And then I realized: We bear the fruit of having started our family right away. Maya was born one year after we married!
Live in such a way that you won't have regrets. I have worked with lots of elderly people and without exception, no one ever regretted having the kids they had, but I met many who wished they would have had more.
