breast milk

Je
Is there a difference between a baby drinking breast milk straight from the breast  or having it either a couple hours after pumping or after defrosting? Nutrients wise. I want my husband involved in the feeding so I'm stuck in between exclusively bottle feeding with my breast milk OR doing a half and half situation (half straight boob half bottle boob) if that makes sense. And more so looking for  any personal experiences. Was one easier than the other? Did your baby prefer one way? Tips!
