Since weight is the best way to gauge how well breastfeeding is going it is a good idea to purchase a weigh scale off of Amazon. This way there will be no surprises when you go to the pediatricians office for a check up. I have seen plenty of babies over the years that this happened to and it is upsetting to the parents. Buy a weigh scale and this could not happen to you. I suggest weighing your baby regularly 2-3 times a week. In the morning before a feeding and only dressed in a diaper. The diaper weighs approximately 1/2 of an ounce.
This scale below is a nice choice because it can be used for your baby and toddler as your baby grows. It weighs from 0.4 of an ounce up to 66 pounds. It comes with 2 batteries and is ready to go out of the box, no assembly required. You can sync it to your phone to track your babies growth. It has a linear measurement to track your infant’s height. It has a silicone bottom so it will not slip off of a table when weighing your baby. For the last few years I have been giving a weigh scale as a shower present to new parents!
