How much and often are your newborns eating? My daughter makes me feel like I'm starving her. She won't drink nomore than 2.5 ounces in one feeding (bottle fed) and she's ready for another bottle two hours later (faithfully) and sometimes she'll take another ounce in between. I tried to up her I take to 3 ounces in one feeding but she won't stay awake to finish.
Sounds like she's doing just fine. She should be eating every 1-3 hours. Her stomach is pretty small now so 2.5oz is probably all it can hold. As long as you are feeding her whenever she asks for it and she is growing and gaining weight appropriately, don't worry :)
