Going to get downvoted for this, but whatever.
It is cruel to mother, father, and child to force a father to take care of a newborn or < 1 yr old without the mother. The newborn is used to the mother's body. A newborn gets stressed being away from its mother and source of food, even when with the dad. Breastfeeding from the breast is not just a source of nutrition but also a source of comfort for the baby, and healthy for the mom (both physically and mentally). Men do not have this need or ability.
Putting a man at home with his newborn, without the mother, is a recipe for disaster. Not because a man cannot do the actions required to take care of a baby in this circumstance, but because, if the woman wants to do the recommended thing for her child (breastfeed him or her), then she would have to pump (which is a lot of work) and store her milk (a lot of work). Oh also, she'd have to do this at work, which again makes her unequal to her male colleagues. The man would have to disinfect and clean bottles, and be unable to soothe a child if he runs out of milk (unless he has formula on hand). The child doesn't get the human touch of breastfeeding.
So to recap... the mother loses because, despite going to work for the sake of 'equality', she's stuck every few hours pumping milk, losing work time her male colleagues can use to further their career. The baby loses because it doesn't get the psychological security of suckling at the breast. The father loses because he is simply less able to calm the baby down and feed it than the mother.
By all means, help men to stay home with their older children. This is great, but a father with a newborn is simply a bad idea, IMO. Formula is possible, but from a public health perspective, it should be discouraged unless necessary.
I will never understand why people make parenting harder on themselves. Newborns are hard enough, but the human body has an easy way to fix it. Whenever my daughter is fussy, she goes straight back to her mom for comfort nursing, and then when she's done, she's back to me for fun times. This is easier for everyone involved, and fosters a positive father-child relationship.
Both my wife and brother-in-law were breastfed whenever they were fussy, and it always calmed them down, according to MIL and FIL. Not being breastfed myself, I didn't believe it at first. But sure enough, with my daughter, literally all problems can be solved by suckling for a minute at her mother's breast. Why make this harder on ourselves? By the time she's back with me, she's happy, laughing, and ready for tickles and fun, and mom can get a well-deserved break.
