should I wean him

Hello all, I'm am planning to get back to work. There is a possible employment opportunity that might happen within a month. My baby is 10 months old and is breastfed along with solids.he spends most of his time with me. I'm really nervous about going back to work.how do I wean him as bottle is not an option for me. He will not drink from a bottle.  Now my question is it possible to get only feed him when I'm home after work or do I completed wean him. I'm really confused. Please give me your advice or share your experience. Thanks in advance
