Decreasing Breast Milk Concerns

I am a working mother of a five month old girl who eats 3-4 four oz bottles while at daycare.

Until a few days ago, I was pumping enough breast milk to fill one and a half of those bottles (the rest were formula) and then breast feeding while we were at home. Today I am barely going to pump enough for one bottle.

Does that mean when my baby is breast feeding at home she is not getting a “full” feed? She definitely wakes up faster after a breast feed than when my husband does a formula feed but I have been trying to still breastfeed as much as I can until six months. :/

At this point I am just pumping during the day to make sure my boobs still have milk for when I’m home but I’m worried she isn’t getting enough?
