It sounds like you are doing fine. My daughter has slowed down on nursing for teething and other times she doesn't feel well.
Is your lo having plenty of wet diapers?
I would keep pumping regardless of what you get to help keep your supply up. If your lo is anything like mine, she is getting a lot of milk in the first couple minutes.
It is probably good not to give too many solids, and to offer the breast often, but I suspect this will resolve itself soon.
