I find myself stressing sometimes about how often my nearly 16 month old daughter nurses. I really want to just follow her lead, but she is such an active little one that I fear she would start to wean herself if I didn't step in sometimes and encourage nursing. Still, she probably nurses at least 10 or some times per day (including night time sessions). She definitely still nurses to sleep for naps and at night. She eats plenty of food too, so it seems nursing is becoming more for comfort. She was exclusively breastfed before we started solids, and she's been a pretty good eater.
So, just curious -- how old is your toddler, and how often do they nurse? I'm guessing there is a huge range in this age group.
