Bottles while at work

Just trying to get some advice. My freezer stash is running low and I’m not pumping as much as I used to. I normally leave 3 bottles for when I’m away at work. I’m debating just leaving 2 as she’s eating more solids but I don’t want my baby to be upset either. I know they’re supposed to primarily have breastmilk but she still nurses at night 😂 Thoughts?
