please tell him to not go around cheating making this an excuse....give some time to the new mom and child to bond...this is very common than you think that the new dad becomes jealous of their own child that the wife's attention is shared...now he is not the onlyone she will go headover heels after....be a MAN and be a good father...sex and all will prolly go on after the wife's hormones come to normalcy....also ask him to read on post partum depression for both parents ( research say that even men suffer from it) ....
