Nope I don't call that lazy at all. That is normal. We can't blanket it all and say any mom who sends her baby to the nursery is lazy, its a specific type of person I think of, the ones who don't want to particpate in care at all, i.e. feeding, changing, etc. Now if we could staff for a person in the nursery it would be even better.
I offer to my moms to keep the baby if they even so much as think/blink or act like they could use it. If they ask, I say sure and ask how they want the baby fed, etc. If I need to do a lab or anything I will ask, do you want me to keep the baby for a couple hours so you can rest? Etc. This way I'm not pushing but they don't feel bad for asking b/c I've presented them with it.
Sometimes you just gotta rest!
