Thank you so much for sharing, hun! A lot of times, babies lose a lot of weight because of poor latching or general sleepiness (I had to wake Miss Maggie a lot to eat; she would go for like 4-6 hour sleep binges. o.o)
so supplementing can work, and we should feel proud that we did at least try once! You are amazing, and the guilt you're holding onto is just a speck of dust on your shoulder. Brush it right off! <3
