Inside Pregnancy: Weeks 21 - 27

"Inside Pregnancy's" fourth episode takes you through the final weeks of your Second Trimester. Your baby's sense of touch is dramatically developing during this stage, and he'll experiment with anything he can get his hands on. You'll see inside his lungs where the bronchioles are already moving small amounts of fluid in and out as your baby practices breathing. His sense of sight and taste has also come a long way.

"This is the first episode in the series that we see the mother, so we really wanted to create a nice connection with her to the baby in the womb. We certainly realize you would never be able to see a hand through the womb and all the layers of muscle and skin... this is just one of those creative liberties we took to get the emotional point across."
