Pumping then went to ebf

My son was preemie so had issues latching in the beginning, so we pumped and supplemented with special formula for the first couple months and I breastfed At night and when i was home. Now I'm breastfeeding all but 1-2 feedings a day. And my son will take a bottle from my husband but not from me? Anyone have this happen? And the past few days all he's wanted is my boob like all day. Is this normal
