Is it normal for an infants weight to fluctuate throughout the day or to not increase from one day to another? I have a feeling it is, fluctuation happen and average weight gain per day is an average, but if anyone could point me to research or articles of amount or ranges, that would be good.
Backstory (if you care): My daughter's weight fluctuates during the day and from day to day may not see an increase. The pedi does not seem worried (says she is right on track) but I just want some hard data.
