how much weight should a 2 month old gain daily?
Remember that most babies lose some weight during the first few days of life, but usually regain this weight over the next few days so that within a week to 10 days they're back to their original birth weight. 1 to 4 months: Babies usually gain 1 1/2 to 2 pounds and grow 1 to 1 1/2 inches each month.
