I haven't done this since I was 2. If then. My wife babysits and got a paci too big for a 6 month old. I washed it off in hot water and stuck it in my mouth. Usually I gag on things in my mouth longer than a couple of minutes, but I managed the paci OK. I felt guilty and took it out and washed it again in hot water. I can't believe how smooth the nipple was.
My AB experience probably won't go any further but I thought I would share.
