Some people may have an issue with dads staying at home caring for the kids while Moms go to work, but I personally do not think there is anything wrong with such an arrangement. If everyone in the family agrees and is happy with that kind of situation, then I think it’s exactly the same as the more traditional practice of women staying at home.
Fathers have their own capacities of nurturing and raising children. I am pretty sure God did not only give the ability to love and care for kids to mothers. As a matter of fact, I have come across various studies that show the positive effects of children in a household with a stay-at-home Dad.
Mothers have their own ways of parenting and so do fathers. I am absolutely certain that both are capable raising kind, responsible, and great kids. Here is a post that looks into the parenting style of Dads, At-Home Dads Make Parenting More of a ‘Guy’ Thing.
