I wash the baby bottles by hand and often let them air dry. Do I have to dry them completely before adding breast milk? I would obviously want to get all of the dish liquid out of the bottles. But I wasn't sure if the breast milk mixing with a small amount of water would have any impact on the baby. I would think that he might just pee slightly more frequently if I don’t dry them fully?
I'm using Dr. Brown's bottles, so drops of water collect on the nipple, bottle, vent, vent cap, and cap.
It's not clear if these trace amounts of water would contribute to water intoxication.
My child is 3 months old.
