It should be noted that, in all of these approaches, the aspect of parental responsibility, which must be shared among parents, is decision-making power. None of the three models explicitly imposes or contemplates a common residence. Florida and Maine explicitly define co-parenthood as a common decision-making power over the child. While the legislation of the United Kingdom and Australia vaguely defines the responsibility for parenthood, commentators and case law have suggested that it encompasses common decision-making powers. It does not involve or require a common or shared physical stay. As a result, all these approaches to common parenthood require that the child`s residency time be allocated separately according to the child`s best criteria. The concept of “common parenting” applies to cases of divorce, separation or non-cohabiting parent; On the other hand, a common partnership between income and housing is a marriage in which partners share almost the same way the work of raising children, earning money, domestic work and leisure in all four areas. Common education is different from shared custody, where some children live mainly with their mothers, while one or more of their siblings live mainly with their father. Variations over changing weeks. The simplest common educational plan is alternately weeks of conservation. The downside of this schedule is that a parent does not see the children for a whole week. For this to work, many parents take the alternating basic weekly schedule and add some variations. A common thing to do is to add an evening visit during the week with the other parent.
Early criticism of common parenthood was based on the assumption (i) that children needed a single primary liaison figure with which they could connect, (ii) that children`s development suffered from frequent back-and-forth movements between two households and (iii) that the status quo should not be disrupted.  Scientific research is supported for and against these assumptions. It is important to consider child-specific factors, such as parental temperament, environmental factors and genetic factors, before trying to determine the impact of a certain style of education on a child`s theory of education. (i) The parent of the household agrees to change the parent or both parents as part of a co-parenting decision that agrees to change the parent`s designation.
