Rutabaga Baby!

The 25 weeks synopis from BabyCenter.com:

"Head to heels, your baby now measures about 13 1/2 inches. His weight — a pound and a half — isn't much more than an average rutabaga, but he's beginning to exchange his long, lean look for some baby fat. As he does, his wrinkled skin will begin to smooth out and he'll start to look more and more like a newborn. His hair is probably recognizable now (in color and texture), although both may change after he's born."

Here is what a 25 week baby might look like:

Pampers Parentpages also adds:

"The brain's cortex is developing into layers. Most of the action is still controlled by other brain areas that developed much earlier. The human cerebral cortex is the most elaborate brain structure in all the animal kingdom, giving us the ability to think, plan, and feel in complex ways."

Other sources have also mentioned that he is also listening to sounds, like my voice as well as others' voices around me.
