Just got done watching the video by Nova online about how a baby forms (https://www.pbs.org/wgbh/nova/miracle/media/2816_r_01.html) And without me asking, nagging, or coaxing him! He was like wow I never knew about all of this before. Hehe....I am so touched that he did that and it really shows that he's really interested in this. I'm just all like "awwwwwwwwwwww" right now! Hehe.
