我觉得这样做会大大地破坏夫妻感情。从血缘上来说，这孩子只和夫妻一方有关系。另一方整天面对“别人”的孩子，肯定心里有根刺。到时候，一方疼爱孩子，一方如鲠在喉，不离婚才怪。

I think that doing something like that can cause great harm to the feeling between a man and wife. From the point of view of blood ties, the child only has a relationship to one of the parents. For the other parent, the child is always someone else's child. This would definitely be a cause of discontentment in their mind. At some point, one parent will love the child, while the other will want to vent their pent up feelings. It would be a wonder if they didn't divorced!
