I have no idea how to use that thing. Do you add the top oz to the bottom? I did Stewie's weight at 16 weeks and I cannot come up with an answer... I've looked that that chart about 200 times and still don't get it.
By the way, the same person made those two sites. Her name is Kimberly and she's a member here (feminvstr)
