For veteran breast-feeders...

Carrie
Hi moms! 
I'm currently 11 weeks pregnant with baby #3 and I've had no change in my breasts yet... No soreness, tingling, they haven't grown, nothing. 
I successfully nursed my older two for 19 months each, but #2 weaned about 18 months ago. 
Have any of you had this happen? I am worried my breasts aren't doing what they need to do and I'd really like to be able to breastfeed #3! 
Thanks in advance!!
