I did a deeper Google search and there are many many women still lactating YEARS later. I definitely feel like I will be this way for a long time.
Jeez. Having a baby REALLY steered me from my pre pregnancy body :(
On the plus side. It's nice to know I have a good supply for future children.

Although I still didn't get too much info on the bumps on my nipples. But I assume it's because I'm not fully empty yet.

I have a friend that has a 5 yr old that she bf too and she still has some leaking every once in awhile. I would just ask your obgyn next time you go for a pap.
