I have been breastfeeding my son since he was born but for a week ive been giving him formula and breastmilk but since my husband bought me a breast pump i want to stop using formula and today i haven't given him any formula just breastmilk but his been breastfeeding for like 2 hrs and his still hungry and it makes me feel really bad cuz i feel like im disappointing him i dont know what to do. How i can produce more or if i should just stop and give him pure formula im so lost i feel like a failure  right now
