From the Twin-Daddy:<\/h2>\n

Hunter-Gatherer checks his calculations<\/p><\/div>\n

Today is Twin Day, and we are 33 weeks along and 3 weeks from hitting our goal of 36 weeks. \u00a0As Mary indicated, we had a big surprise when we got a look at the boys and found out that they were ahead of schedule again weighing in at about 6 pounds each.<\/p>\n

I am an engineer by trade, and we have been collecting a good bit of data. \u00a0Using the length measurements and the average baby sizes from babycenter.com<\/a>, I was able to estimate weights based on length measurements and estimated gestational age from each ultrasound we have had over the course of the pregnancy. \u00a0It is important to remember that some of these weight numbers are calculated from average gestational age<\/a>. \u00a0Even the measured ultrasound weights can have a margin of error of plus or minus 15%.<\/p>\n

Plugging in the data, what we got was an exponential curve that significantly outpaced a typical singleton baby. \u00a0You can see how each boy is growing in this chart:<\/p>\n

Aside from reaching 36 weeks with the boys, Mary\u2019s other goal has been to get the guys to 6 pounds each. Now that they’ve reached that initial goal, she’s eyeing 7 pounds each. \u00a0If their average growth rate continues as it is, how long will that take them?<\/p>\n

7 pounds = 3175 grams<\/strong><\/p>\n

Alex and Dominic at current weights:<\/h4>\n
    \n
  • Alex = 2805 grams<\/li>\n
  • Dominic = 2643 grams<\/li>\n<\/ul>\n

    In the last 4 weeks each of our boys gained weight as shown:<\/h4>\n
      \n
    • Alexander gained 1252 grams<\/li>\n
    • Dominic gained 951 grams<\/li>\n<\/ul>\n

      The average of these two weight gains is:<\/h4>\n

      \n

      1252 + 951 = 2203 grams<\/p>\n

      <\/span>2203 \/ 2 = 1101 grams<\/strong><\/p>\n

      1101 grams \/ 28 days = 39 grams gained per day<\/strong><\/p>\n

      Since Dominic has slipped out of first place and weighs slightly less now, we will use him as our benchmark for 7 pounds. \u00a0(If he reaches 7 pounds, we can assume his brother has also reached 7 pounds.)<\/p>\n

      Additional Weight Required to Reach 3175 grams (7 pounds):<\/h4>\n
        \n
      • Alex = 370 grams<\/li>\n
      • Dominic = 532 grams<\/li>\n<\/ul>\n

        532 grams required\/ 39 grams per day = 13.64 days<\/span><\/span><\/strong> until the boys reach 7 pounds<\/p>\n

        Round that up to 14 days<\/strong><\/span><\/span> to predict that we reach our target weight by August 5th.<\/p>\n
