FF for bedtime?

ssmb_clarinet

My DD is 9 weeks old and I EBF. I have to pump while I am at work so she has bottles for daycare. I have been having the hardest time pumping enough for her to eat while I am gone. She gets 4 to 5 bottles a day at 3oz. each. This has been stressing me out for the last 2 weeks and the stress is not helping me pump more. Would it be the worst thing in the world if she has a formula bottle at bedtime and I could pump at that time to replace her feeding so she had enough for daycare? Would that hurt my supply even more? Part of why I want to do this too is that my supply dips in the evenings and she never seems satisfied so she does not go to sleep well. Thanks for any advice!
