I just want to be sure that I'm interpreting Kellymom correctly where the website says to calculate weight gain from baby's lowest known weight. This means that when I'm calculating how much weight my son has gained on average, I go from that lowest known number, correct? Do US peds usually look at weight gain this way? LO was 9 lbs at birth, then dropped to 8 lbs 8 oz on day 3, and when we weighed him on day 23, he was 9 lbs 15 oz, having gained an average of .79 lbs per day since his lowest known weight. But it's only .72 oz per day since birth. I'm just hoping our ped will be satisfied with our LO's weight gain at his checkup tomorrow. Thanks!
