Re: Is it possible to dry up from improper latch?
Forget how the latch looks. Concentrate on how it feels, and on diaper output. When the latch feels okay and baby is peeing/pooping enough, things are probably fine. And as LLLMeg said, put away the frozen milk and just nurse, nurse, nurse! Let your baby's cluster feeding do the job of establishing your supply at the right level. You don't need to feel full or engorged in order to have enough milk. In fact, feeling full/engorged all the time means you have too much milk, and that's not something you want to do in the long term because it's a waste of energy and puts you at increased risk for plugged ducts and mastitis. What you want is to make the right amount of milk- and when you do that, it's completely normal to feel soft all the time.
