Question about feeding past 6 months-where's my milk?!?

Have you had any periods since giving birth? I noticed that my milk supply seemed low when I was on my period, there's an herbal tea called 'mothers milk' and everytime I was starting my period I noticed my milk supply low, so I would make this herbal tea and it really helped!! I've been feeding twins for 2 1/2 years now, and there's a lot more milk in your than when you pump, so even if your pumping less, there's still plenty of milk for your baby when she's eating from you. Good luck. hope this helps.
