1.5-2 oz every 2 to 3 hours. Also use a preemie or slow flow nipple and have any care givers pace feed.

My son was eating about 3 oz every 2-3 hours. He now eats 5-6 every 2-3 hours

At that age my son was drinking about 1.5- 2 oz every 2-3 hours. My son drank 4oz until he was 7 months old. He's just now starting to take 6oz.

My 6 month old son has 3-4 oz of breastmilk at a time. At 2 months he was having 2-3 oz at a time. I only work part time so we still breastfeed most of the time!

Try putting some in a bottle and see how she does start with 2 or 3 oz and if she does fine a feeding with that send enough for that if she still seems hungry go up to 4 or 5. My one month ranges from 4-6 oz depending on how long she goes between feedings
