We are a monogamy-normative world so people believe children would be better off being raised by two [preferably opposite gender] individuals. People cannot believe that loving polyamorous relationships exist and won't harm children. [It's the jerks in society that harm children.]
Really, the biggest drawback is it makes it easier for cult leaders to have multiple wives, but I think that children shouldn't be allowed to marry even with parental permission, so I consider that a secondary point.
For instance a man works a 9-5 job, has 3 wives, each with 3 children - that's 13 mouths to feed in total. The mothers likely won't work while they bare the children and while they raise them... Who will pay for all those children? I'm not sure how it works in the US but in the UK, for every child you have you get more benefits. 9 children with one father, no way is his wage going to cover all the expenses. So the government will be paying out for the kids. While other monogamous couples will have a father who only has to pay for 3 children instead of 9.
