Do you care sharing with me how many ounces of milk does your 4 month old babies drink and how frequent? As I am planning to increase my baby's ounce but I am just afraid that I am going to overfeed her.

At 4 month old my baby was drinking about 120ml of breastmilk every 4 hours. However it fluctuates depending on her mood. Sometimes she only takes about 90ml every 4 hours. Do take note that baby boys may tend to drink more than girls and every baby drinks different amount anyway. Only your baby will know what amount is enough. What you can do is to increase the feeds gradually (if baby finishes the bottle) and increasing it till there's leftover consistently for 3 feeds then you will know what is her intake. At 4 months her cycle should be a 4 hour one.
