Books on babies for kids, what would you have done?

So this is one of the three books I bought to read my almost five year old. 
Then I got to this page and the part where it said "mommies have one piece" then saw the rest, stopped and moved in to the next page..
I felt like it was just a tid bit too much information for her age...reading about the birth canal was bad enough haha! I'm terrified of her being the one when kindergarten starts teaching all the other kids how babies  are made lol
Would you have skipped it too?
