This scene reminds me of Chapter 10 Bittersweet Love. From my fanfiction: Harry's Little Dividend. It is a heartbreaking scene. The Chipmunks and Chipettes are down in the living room; while upstairs comes the agonizing scream of Vinny, who is going through a difficult labor. Brittany and her sisters weep for her. The boys and girls had just gone through a growth spurt. So this is how they would look like.
