At the risk of sounding like a worried older brother…
Growth might increase more at some times rather than others. Also if you lose fat or water, it might appear you’re losing rather than gaining. Do you have a scale or device that might track body fat? Even so, the measurements can fluctuate due to “error” that is in the scale or device.
What if you had a “weigh in day”? As in once a week you take measurements. I’m wondering if too much monitoring might lead to over-concern about gain and then lead to stress and then lead to cortisol elevation, and then I think you know what I’m getting at.
