He's been doing this for 2 or 3 weeks now. Started when we bought scented wipes by mistake but now he seems to do it all the time, sometimes even putting them down his pants and saying "smell,they're not stinky!" . Generally he just holds both sets of fingers up onder his nose like a squirrel holding a nut and inhales quickly 3 times. It seems almost compulsive and it's getting very weird. Please tell me you're well adjusted child grew out of the same thing within a few weeks.
