How much do your LO's eat? And how long do they nap and sleep at night? My DD is eating about 2-4 ounces every 2-3 hours and every 3-4 hours at night. She will take just one longish afternoon nap (2-3 hours) and then sleep from 9 pm till morning (waking up to eat).
Re: 6-week babies?
DD was eating 4oz every 3-4 hours, usually napping in between bottles for about 1 1/2 to 2 hours (awake the remainder of time) and sleeping from 11 to 7 at night.
Now, she eats 5 1/2 to 6 oz every 3-4 hours but basically sleeps the same with a few extra hours awake spread throughout the day.
