Honestly I disagree that it's bad advice. The advice I give to a lot of new dads specifically is that Moms #1 job is to take care of baby, Dads #1 job is to take care of mom AND baby. Even if the little one is formula fed, the weeks/months after childbirth are so difficult for mothers. Sacrificing yourself a bit, in my opinion, IS balancing the work.
As time goes on and you have a toddler, things even out significantly.
