My twins aren't 2 moths yet till the 13th but they eat 4-5 oz every 3 hours. My dr said I was over feeding them, to feed them less & more often. But that doesn't work. They will just cry & cry all day. So I kept doing what I'm doing & feeding them what they want. They seem to be ok. They don't throw up or anything.
Maybe try 6 oz see if she gets full she's at the growth spurt age so maybe she just isn't getting full 😀 I went threw that with all 3 of my boys @kylamommy2016
