RT Journal Article SR Electronic T1 On triparenting. Is having three committed parents better than having only two? JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 735 OP 738 DO 10.1136/jme.2011.043745 VO 37 IS 12 A1 Daniela Cutas YR 2011 UL http://jme.bmj.com/content/37/12/735.abstract AB Although research indicates that single parenting is not by itself worse for children than their being brought up by both their parents, there are reasons why it is better for children to have more than one committed parent. If having two committed parents is better, everything else being equal, than having just one, I argue that it might be even better for children to have three committed parents. There might, in addition, be further reasons why allowing triparenting would benefit children and adults, at least in some cases. Whether or not triparenting is on the whole preferable to bi- or monoparenting, it does have certain advantages (as well as shortcomings) which, at the very least, warrant its inclusion in debates over the sorts of family structures we should allow in our societies, and how many people should be accepted in them. This paper has the modest aim of scratching the surface of this wider topic by challenging the necessity of the max-two-parents framework.
