3 month old is refusing to breastfeed

Kv

Before I went to work we had no issue breastfeeding she latched on the moment she was born. And I’ve been back to work for 3 weeks now but this passed week when she’s really tired she refuses the breast she’ll scream and cry and not take it. I pump at work and bring it in the next day at the daycare. But today I’m off and I’m trying to breastfeed her and she refuses. During her night feedings and morning she has no issue. But now during the day and before going to sleep she refuses. Do you have any tips ? I’m feeling so depressed about this because I love breastfeeding her when we’re together.
