Need advice on breastfeeding

Ni

So my baby will be one soon hes my 3rd child. My older kids are 4 and 2 so when I had my youngest I was exclusively breastfeeding if im honest I just couldn't fit in expressing any milk between the constant feeds and also having 2 other children to look after! Now I'm completely stuck because he refuses to drink any type of bottle. I still love feeding him and I don't want to wean him off me completely though. He takes 3 to 4 spoon feeds per day and finger foods now and again but he's still so unsettled without me, I can't even leave him to work because he will not drink anything. What can I do please i honestly don't want to buy a new pump and start expressing milk if i can help it
