Since my daughter is already more than a week old, and thriving well, our lactation specialist told us there was no need to wake her up any more to feed her. We could just let her sleep until she 'asked' to be fed.
So we do. And her nights have been growing steadily longer, culminating in a 7 hour stretch this night. We fed her at almost 10 PM last evening, and she hasn't made a peep until now, at 5 AM! And even then, she only kind of coos and giggles. No crying. No screaming.
This may very well be a 'honeymoon' period. But she still is, by far, the best little kid. Ever.
