I have read something funny before about mothers being more dedicated, therefore bonding more with their children than the fathers do. It also stated why maternal grandmothers are more generous and loving of their daughter’s children vs. their son’s. The mother and the maternal grandmother know beyond a shadow of a doubt that the children contain their genetic material. This is also why a parent’s favorite kid tends to be the one most like them. I bet your kid looks just like you flu :).
It is typed to be a joke,though there may be some scientific evidence. I think we are bigger than that. I dated a woman with two children and even though they were 4 and 6 when I met her and they loved their dad,and they were brown and I am not, I could have loved them like my own.
