7 month old

So we started my 7 month old on baby food around 4 months old because she was showing significant interest in food. At 7 months old she is up to 3 meals a day plus breastfeeding. I had noticed a slight dip in my breast milk once she started food but I was still able to pump what she needed to eat for daycare. The last week my supply has significantly dropped and she is showing no interest in breastfeeding except for at bedtime. She latches and unlatches through a feeding and then wants a jar of baby food. She is my first baby and I am the ONLY one in my family who ha breastfeed. I am not ready to stop and I know she is too young. What do I do???
