My daughter just turned 3 months old. She has started sleeping through the night now and wakes up at about 7:30am. She gets a bottle at 8am, 12 noon, 4pm and 8pm. She is taking 5 ounces at each feeding. This only really equals to about 20oz since she is missing her night time bottle. Do I need to up her bottle to 6 ounces so she is getting more ounces in throughout the 24 hour period or is she eating enough? She seems satisfied at each bottle and stays on a good schedule with her feedings but I keep reading everywhere that she should be taking 24-30 ounces... Any advice?
