Relactation

Anyone ever try to restart their supply after it dropped? I’m 2 weeks PP and stopped producing milk for about a week, we had visitors visiting so it was hard to try and pump & breast feed with visitors, I already wasn’t making enough so we were supplementing with formula, I haven’t made any milk for about 6 days. Has anyone had any luck with restarting their supply after dropping for a little? Baby is doing good with formula but I really want to try breast feeding one more time with him.
