S.T.
I tandem nursed when they were little and while it was overwhelming at times my two kids, age 12 and and 9, now act like they are twins. They are close, closer than most kids. They don't have fights. They might disagree, and they might not always see eye to eye but they treat each other with respect. I can't say for sure it was the tandem nursing, but 9 years later I think it was part of the reason why they both love each other and we don't have the sniping and name calling that other families have.
