Just thought I'd share a personal story.  Child #1 weighed 7 lbs, 13 oz at
birth.  I breastfed her through my pregnancy with Child #2, who weighed 9
lbs, 15 oz at birth.  I tandem nursed both until Child #1 weaned at age 6.
 At that point, Child #1 weighed forty pounds.  Child #2, who was only 3
years old (and continued to nurse) weighed forty pounds.

I like to tell this story whenever a health care professional cautions me
that breastfeeding during pregnancy or tandem nursing causes irreparable harm
to the younger child.

Best wishes,
