It's a ted talk (if you didn't get it from the link lol) but in it they go over how quickly our babies are developing right NOW. For example, I am 8 weeks as of today, my baby is 42 days old. (simply take 2 weeks off your length of pregnancy and multiply what week you are in by 7 and add how many days you are to it, if you want an idea of where in this video your little one is, eg: I'm 8w0d, 8-2=6, 6x7 is 42 +0 is still 42)
Wadsworth constant applies if you want to go straight to the growth video and not listen to the scientist (skip about 1/3 of the way in)
My favorite snippet: if our babies continued to grow at the rate they are growing at now, in 9 months they would weigh 1.5 tons.
