Exploring Baby Weight Mathematically

A baby's weight changes dramatically in the first weeks of life. For example, let's look at data for Baby Kevin and Baby David.

Baby Kevin:
TIME birth 2 weeks 8.5 weeks 17 weeks 26 weeks
WEIGHT 7 lb, 6 oz 7 lb, 6 oz 11 lb, 7 oz 14 lb, 8 oz 16 lb, 5 oz

Baby David:
TIME birth 3 weeks 4 weeks 5 weeks
WEIGHT 7 lb, 9 oz 8 lb, 14 oz 9 lb, 12 oz 10 lb, 6 oz

The graph below tracks Baby David’s weight and Baby Kevin’s weight over time.  David was only 5 weeks old when this graph was made.  For fun, I created equations to model the data, which you can see by clicking here. With these equations you can answer some interesting questions.
