spinoff to sleeping through the night

Ever since my ds started sleeping between 5-6 hour stretches at night I have noticed a big decrease in my milk supply. I know there is a supply and demand issue, does anyone wake themselves up three hours through and pump to keep their supply up? I am worried I am going to have to start formula earlier than planned ( I pump milk exclusively).

I don't know but I know that certain foods can increase your supply like oatmeal.
