Breastfeeding A to Z

Weight Check–2 Week

At a two week weight check, your baby will be expected to be back at their birth weight or beyond it.

If you aren’t sure how your baby is doing, a weight check is a quick way to know if they are getting enough to eat.  They will normally be gaining 1/2 ounce to 1 ounce per day (15-30 gm/day). (1)  During growth spurts they can sometimes be gaining 2 ounces (60 grams) per day.

When having your baby weighed, they are usually weighed nude or with only a diaper on–these two ways are preferred for consistency.

If there is a question about the baby’s weight, double check if the scale is read in kilograms or pounds, or if they are converting one to another.  Many scales have both readings, one on the top of the bar, one on the lower part of the bar.  If a digital scale is used, is it set to read in kilograms or pounds and ounces?  If there is confusion ask someone else to weigh the baby or to reweigh the baby.  If available try a different scale.

Keep in mind if your baby was weighed on a different scale or with clothes on it will change their weight.  In these early weeks, it makes a bigger difference because you are dealing in ounces of weight gain, not pounds.
