What happened to Adam and Eve when they sinned?

I was delighted (again) to see, through the Catechism what Elisabeth is learning. I read to her question 37:

What happened to Adam and Eve when they sinned?

Although the "correct" answer is, "They were separated from God" (Genesis 3:24), Elisabeth answered,

"It was hard to have babies, and getting food was hard."

That is a very good 3-year-old paraphrase of Genesis 3.

"I will surely multiply your pain in childbearing;
in pain you shall bring forth children. . .
cursed is the ground because of you;
in pain you shall eat of it all the days of your life" (v. 16, 17).
