how much milk to send to daycare?

Meagan
I have a 12 week old daughter and will be going back to work on Monday (😭😭😭) I've been breastfeeding and pumping, but since I almost exclusively BF my baby I have no idea how much she eats each session. I have 3oz baggies of milk, at 3 months should they be eating more than 3oz each bottle? Or is that average? How many bags of milk should I send?Â
