I am a pretty visual guy. I am also a numbers guy. Last week while I was sitting in a clinic waiting to see a patient I had with me a growth chart for fetal weight while still in utero. The idea is that you look up your weeks along in pregnancy and reference it to a chart that tells you approximately how much the fetus should weigh, how long it is, and a few other vital statistics. Just looking at the numbers I could tell there was a great curve, but I just had to plot it out to see it.
So here it is. Below is a chart that plots weight in lbs. over weeks in the pregnancy.
It is a rather logarithmic curve, not a linear one, and as would be expected, near the beginning of the pregnancy the fetus weighs almost nothing. In fact, it weighs less than a pound until around week 23 out of 40. But somewhere around week 25 to 27, the weight just explodes, the gain accelerates and takes off; the very nature of a logarithmic curve.
In the version below, I think you can guess where Jess is on the graph.
So, being the amazing husband that I am, I pointed this out to her. I will let you guess what her reaction was.
