How can I tell if my supply is adequate? My baby is six months old eats on demand but recently became distractable so has been leafing less frequently. She seams to have enough diapers but I just feel empty all the time. Last night she slept from 6:30pm-4am and I did not even feel the slightest bit of fullness. She usually nurses at night. Please help I am scared she is not getting enough to eat and that my supply is drying up.
