DD takes about 4.5 ounces at both night feeds and the dream feed. During the day she will take about 2.5-3 ounces and be totally done. She goes 3 hours easily between feeds. Is this normal? Should I be working harder to get more in? She has done a few nights of 6 hour stretches but these are never back to back and mostly wakes earlier around 2:30ish for her first feed. I loved the night she woke at 5am and not again until 8!!!!
