I'm still nursing my 21 month old and am 17 weeks along. I'm planning on nursing him to at least two and maybe tandem nursing. How many of you all are still nursing? Are you planning to wean before the birth or tandem nurse? Has anyone had supply problems? I haven't gained any weight so far, and I think maybe it's partially because I'm breastfeed -and- growing a baby. (Hey, fine by me!) Do you think you're more tired or hungry because you're nursing?
