Re: my whole day is feeding
It's rare for a baby to be blasé about not getting enough to eat. Most babies who aren't getting enough let mom know by nursing constantly and crying the moment they are put down (though both those behaviors are also common in babies who are getting plenty to eat).
If your child is getting less than his daily calorie needs, he's not going to grow or develop normally. It won't happen right away, though. A few days of not getting his calorie needs met aren't going to hurt him, because he'll just metabolize some fat stores, and devote that energy to the most important aspects of his growth, like brain development.
