Sending milk to daycare: first time momma has some questions! Help is so appreciated.

Hey ladies! FTM here and baby boy will be 4 months when he goes to an in home daycare. He eats every 2-2.5 hours but is exclusively breastfed and I’m not sure how many ounces to send to daycare. At night, I let dad feed him a bottle before bed and he’ll eat anywhere between 2-3 ounces but then usually fusses until I let him fall asleep on the boob. 😂 I’ve read babies generally don’t eat more than 4 oz a feed, so do I just go by that and send 4 ounces per feed? I have 400oz in the freezer and I think I’ll send a mix of fresh and frozen milk. I’ve been storing in 4 oz bags so of course I’m worried about wasted milk too... He is eating at 6:30am, 8:30am, 11:00am, 1:30/2:00pm, 4:30pm and 6:00pm. Some days he’ll have to have all of those feeds at daycare, but generally the last one will be 4:30pm. I’ll be pumping at work (I guess 3 times a day.)

Here’s my cutie pie. 😍 Thanks for the help, ladies.
