How many ounces

Coco

I want to introduce my baby to a sippy cup, is this good or bad ?? He’ll be 7 months on June 6 th...how many ounces of milk does a 7 month old drink, in a day... or how many ounces per feeding ?? (Assuming he no longer comfort feeds through the night)... I want to make sure he’s getting enough milk, to get full during the day.. I EBF, as of now, but would like to start having him drink breastmilk from a sippy cup for at least one day feeding... is this a good idea? Not sure🤔any advice ? Having baby eventually drink from a sippy cup , full time, is where I’m headed...hoping by 9 months old he won’t be feeding through the night anymore
