Spitting up every time??

Ftm here and my 4 month baby girl still spits up after every breastfeeding with the exception of when she's breastsleeping. Is there any reason why she's still doing this or when it will let up? I've been using receiving blankets as burp cloths because it's usually anywhere from 1-3 ounces that it seems she's spitting up
