Second week at work, low pump output

It's my second week back to work and so far, I've been able to pump around 9-10 ounces for my 4.5 month old. I also do a middle of the night pump to bring her total to about 12 ounces for daycare (7:30-4:30).

Total I only pumped 7 ounces with stress of the new school year and finding a routine with students being at school for the first day. What I have read says to only send what you pump and baby will make up the rest in the evening and night. I'm cool with this but hoping someone else has experience sending so little to daycare. I feed her right before drop off and immediately at pickup and she eats about every 2 hours. I was thinking I could do 4 bottles of 2ish ounces each.

Should I add some frozen and risk telling my body that's enough or only send what I pumped and try to plump her up tonight and after work?
