To me, this goes along with some of the dangers in the rise of attachment parenting. They're philosophies that privilege intense time / labor on the part of the parents for the benefit of the children -- which is fine if that's what you want to give your children and accept the sacrifice to yourselves. But almost always, it's the mother who is expected to shoulder the burden of that lost time and additional labor, sacrificing career, relaxation, hobbies, and more.
I was a semi-attachment parent by default, I suppose -- I wore my babies in a sling pretty often, tried to breastfeed (with limited success), didn't let them cry it out at night. (Although I regretted that last decision often.) But since Kev is a professor too, his schedule was really flexible, and he did and does do close to 50% of the child-rearing in terms of time and labor.
Many families who choose attachment parenting don't have that flexible job option, and I worry about the long-term consequences for this generation of women who are being told to give so much to their children. Yes, it's rewarding to pour time and attention into your kids. But I'd ask you to be careful you don't give up too much of yourself.
How much is too much? Only you can answer that. But please don't let your husband or your social group pressure you into that decision!
