How do I make small changes in my trust???

Hi.  Making a change to your trust to alter the ability of your beneficiaries to withdraw all the money from your bank account in a lump sum is actually more involved than you might think.  The best way to accomplish this goal would be to contact an estate planning attorney and create a "restatement" of your trust.  The restatement is the most complete and secure (i.e., least likely to be successfully contested in court) method of changing how you want your beneficiaries to get access to your things when you're gone.
