Re: Low supply...
SNSs and fenugreek can help. For some moms, they are all that is needed. For others, more is required. I will say that herbs and SNSs are not nearly as effective at increasing supply as frequent and complete emptying of the breast using either baby or pump.
You can lose a lot of supply in a short time, if you're one of those moms whose body responds that quickly. But most of the time when a mom feels like she has lost supply, she's mistaking a normal adjustment to supply for low supply. LLLMeg's question about why you think supply is low is really important- if you can tell us exactly what is making you think there's a problem, we can either reassure you that it's normal or suggest specific steps to fix it.
If you EBF and baby falls asleep, that's a good indication that no supplement is required. It's rare for a baby to fall asleep when still really hungry! If you're in doubt about baby's intake, watch her diapers: good diaper output = normal milk intake.
