we concieved our ds when dd2 was nursing at 2 1/2. my period had returned when she was 24 months. we were not ttc. dd2 nursed throughout my pg, during labor and for 6 months after he was born when she weaned just before she turned 4. nursing while pg and tandem nursing was not always wonderful for me but i did not want to take away from her what i felt was her right to bf and wean when ready. it was uncomfortable when she would nurse for the last couple months of my pg. after ds was born i had a serious aversion to nursing her because her mouth just seemed soooo huge compared to his!

i recieved a lot of support here for sticking with tandem nursing and i am very grateful that i did. all of my kids have a beautiful loving relationship with each other. if i had to plan it, i would not choose to nurse during pg and tandem nurse again.... i would ttc after the current baby weaned. that's just my opinion, though
