13 mo waking frequently

Ok so my daughter has been breastfed since day1. Never taken a bottle etc. Shes beendoing well with solidsso theoretically she shouldn'tbe hungry over night. So as of late my supply seems to have taken a major dip i assume from her eating more solids and such which is fine but at night sge has suddenly started wanting to nurse like every 2 hours again. Prior to this she would wake once or twice a night to eat. Im just at a loss. Ive been debating completely stopping nursing just because i want her to learn a new sleep coping mechanism. Im exhausted and in literal pain from how much shes nursing all the sudden. I gues.sim just looking for advice or experiences that you all have had
