Maci - congrats. I also breastfeeding my 16 month old and i only nurse her morning and night, I stop pumping at work. I still haven't had my period. I want a second baby. Did you start your period during breastfeeding?
In fact, you could breastfeed all through pregnancy and continue straight in to feeding the next baby. My sister did that, and nursed both kids for a while until she weaned the older one. Talk to La Leche League if you'd like more information.
My baby boy self weaned at 18 months when I was about 13 weeks pregnant. The taste of the milk changes while pregnant.
It took a few weeks to dry up. Now I'm 36 weeks pregnant and the colostrum has returned. . So yea I'd say the milk returns
I would imagine it would. When I was nursing I got pregnant and my supply took a hit and I really wasn't able to nurse anymore. I had no problems when the new baby was born. Best of luck and congrats!
