Earlier quoted context omitted.
A counterpoint: A friend of mine had a kid a year ago and he found it impossible to take care of the baby when he tried being the caretaker while the mom was away (can't breastfeed, milk in a bottle is not the same). The experience has convinced him equal parental leave is a terrible idea.
Counter counter point: I am a father. Took 5 months off. Baby was breastfed. How? Mom was pumping milk at work, after her lunch break. We put it in the freezer. I was waking it up and giving it with a bottle to my daughter. Diapers/food and so on can be taken care by both genders. It is not easy. Actually, at the end, I was looking forward to going back to work and sending my daughter to daycare, once she was 1 year…
This isn't breastfeeding, unfortunately. Your baby was fed breast-milk, but not breastfed. Not a value judgement, but a father feeding a baby from a bottle isn't exactly the same thing developmentally.
