Breastfeeding Journey

Angela
I hate to say it it I think my breastfeeding journey is coming to an end. My son is 6 months old and I have thoroughly enjoyed this bonding time with him but the only time he seems interested is the first morning feed. I don't seem to satisfy him if I offer it to him any other time of the day. He is also starting on solids so I dont know if that has anything to do with it or not.
I pump 2-3 times a day at work for 20-30 min a time and was getting 3.5-4 ounces each session. Now I only get 1-1.25 ounces each pump. Does this mean my journey is over? If so, this saddens me. I was hoping to continue until he was a year. What should I do? Any advice would be greatly appreciated.
