I stuck 3 cuttings like a week ago and the buds are starting yo buldge and leaf ou at this time , what do I do next?
I am so new to cuttings , do I leave them in the little pot I put them in a few more days or weeks or after they get bigger?

leave them alone, i have killed more cuttings by disturbing them too early. let the roots grow big and strong

I placed multiple mulberry cuttings a month ago in a 5 gallon pot and other than keeping them moist, wont repot them for a few more months. Be patient and give the roots a chance to grow well before moving them.
