Stopped breastfeeding but would making porridge with breastmilk be beneficial?

I still feel so guilty I had to stop exclusively expressing. It was taking over my life with a toddler at home also.

I can still squeeze milk out quite easily. I was wondering would hand expressing and even making his porridge in the morning (I'm going to start weaning this weekend) be beneficial. I know it would only be like 1-2oz of breastmilk a day. Do you think its a waste of time or would have a benefit?
