@kismet_carri, she eats 4 to 5 ounces every 4 to 6 hours....usually it's 4 every 4 hours but if she goes longer without she will eat more. if she goes less then 4 hours she may only eat 2 or 3 ounces. before bed I make her 7 ounces...she may eat less. she's in bed by 1130 and sleeps until 5 to 7am and will sometimes eat 2 to 4 ounces and go back to sleep. she's been eating 4 ounces since 2 months. babies know when they are full and will stop eating or will spit up a lot. her pediatrician told me there is no set for feeding babies and that each one is different...I was worried at her 2 month check up because she was 12 pounds lol.
