Dumb question about bottles.

My LO is going to be attending daycare in two weeks and I’m not sure if 4oz is enough for each feed? She’s 11 weeks old and takes a bottle just fine, we just don’t give her one often so I’m not sure on the amount.

My husband gave her a bottle tonight, it was 4oz, he burped her, we played a bit and then she got fussy. I gave her her paci and now she’s comfortably lounging in her boppy. Would you mama’s say that she got fussy from playing or being close to bed time? If she were truly still hungry she would be spitting her paci out right?

I’m sorry, it’s a really dumb question. I just want to make sure I send enough to daycare!
