My DS will be 5 months old on the 23rd. Currently, I give my sister an average of 8 to 9 ounces of EBM to feed him throughout the day (she has him for about 8 hours). Since he is getting older, I know his tummy can hold more milk. So, I'm wondering how much should he be eating at one time? I give my sister milk in bags (portions range from 2 to 3 1/2 oz per bag) but I think she's been giving him 4 ounces at once..which sounds like a lot to me. I think it would make more sense to give him no more than 3 ounces at a time, since I highly doubt he's getting more than that when I b/f him. I know they say it's easy to overfeed a baby with a bottle. Any thoughts/advice?
