If baby is clearing the bottle, I always add an extra oz to try to prevent taking in air. If baby chooses to drink that oz it's there. X
My little one is exactly the same! He is 2 months and On 5oz every 3-4 hours and still wanting more so going to up to 6oz but was worried about over feeding too! But I suppose there can’t be anything wrong with a full tummy xxx
If she's hungry and not spitting up etc then you're not overfeeding. She might be going through a growth spurt...I go by what my little boy wants and needs not be the tub as sometimes he needs more and sometimes less
