I have a question, My grandson is 7 years old and has this habit of putting his tongue on everything. when he's in say mcdonalds hes licking the table, my daughter brings him to the park and he's on the swings licking the chains of the swing. he licks the walls and everything. has anyone else ever heard of this? does anyone know why he may be doing this? with all the germs out there this is really making me nervous for him...
...would this be considered OCD?
