Ican, why not leave your son's room for now? No need to put a potential trigger in your way. Leave it until you have 90 days or more.
I am similar to you with my emotional triggers and feel that in early sobriety we have to focus on activities that keep us sober and will not serve as triggers. Do fun things, cook, meet sober friends for lunch, take some walks, go to a meeting, etc.
You are doing so well, Ican. Keep it up!
