It sounds like you're doing really well--I'm so happy for you
In the US wing of AA we have a tradition where newly sober members pick up a white chip then different colored chips at monthly intervals up to 6 months; followed by a year chip and a 18 month chip. After 18 months, members pick up chips for their yearly celebrations often choosing special people to give them their chip. The first 6 chips are like colored chips and then they become sort of like large AA coins. I remember when I picked up my white chip I carried it everywhere with me until I picked up my next chip.
Even if you guys don't have this tradition, its fun to have something to mark the celebration of your sobriety, so get a white chip to hold on to for your first 30 days in sobriety
