Moms ask me how do I know if my baby is getting enough milk.  Unfortunately (or fortunately), we don't have ouce markers on the side of our breasts so we need to check other ways.  An infant over 6 days of age should be wetting 6-8 times per day and pooping 3-4 times per day.  To see if a diaper is wet, just hold a fresh one in one hand and the used one in another.  You will be able to tell the difference in the weight of the diaper.  Also, a baby between 2 weeks and 6 months should be gaining 5-7 oz per week.  So nurse with confidence!
