I nursed both for 15mths. Had to wean for different reasons with both, I wanted them to self-wean. I find it odd how at the 15mth mark I had to wean both for separate reasons, is that a magical number? LOL! Perhaps #3 will be able to go further in the future haha! I wouldn't feel guilty weaning at 18mths, that's still an amazing success!
I drink (or at least used to) a lot of coffee, so a lot of pats of butter add up in the calorie area LOL!
