Baby weight at birth 6 1/4Ib(6.25Lb)
At 3month 12 1/2Ib (12.50Lb)
12.50Lb - 6.25Lb = 6.25Lb
at 3 months baby gained 6.25lb(double the birth weight)
when you want to calculate the change in weight in Ib calculate the
one weight to next by subtracting smaller weight from the larger
weight.
set the equation in larger weight - smaller weight = weight gain or
weight loss
