Holding on to baby clothes

So it’s been a year since my son was stillborn and I still have all his clothes bottles just everything I brought him. I don’t want to give it away but I also I don’t plan on having a baby anytime soon. But I know I can’t keep everything forever. Please help I feel like this is the official last step of saying goodbye and reality setting in that he will really never be here.. please give me advice on how you ladies dealt with this.
