Hey! Go check out the "You! The experience" exhibit. It's free with admission and it's got a big section about fetal development and how mama's body changes through the pregnancy. I couldn't find info about how long it's running, but it looks super cool!
It's actually pretty cool. I saw it a few months ago. They took the babies that were just on their own and made them a part of this bigger exhibit. There's an interactive part and a video as well!
