So my daughter is 6 weeks. She was on 3oz every 2 hrs during the day and then I'd let her wake us for night feedings. During the day I'd wake her to feed her which would take 30mins then we'd play, change her diaper and put her down for a nap, next thing I knew it was time to wake her again to eat. So she was getting an HR Everytime. Well the last week her night feedings she's wanted more so I'm giving her 4oz at every feeding every 3 hrs but she still won't nap longer then an HR and you can see she wasn't ready to wake up. She sleeps great at night.
