Breastfeed to bottlefeed help

Shivi

My newborn is 7 weeks old and I am trying to train my son to bottlefeed ( with breast milk ) since I am heading to work soon . I have tried many bottles , with someone else trying to let him feed but he won’t latch the bottle . I am super tensed as he won’t take anything besides my breast . I have tried since past two weeks ( one or two feeding a day ) does anyone k ow how to handle for this . Please help !
