He Licked It
One of my daughter's has Aspergers. She has two son's with Autism. They all live with me which is good. The youngest of the boys is 4 years old. He and his brother have always licked things but his brother who is 5 years old has grown out of that, for the most part, thankfully.
The 4 year old has not. We have to watch him when we are in different places to be careful what he might lick. I got a new recliner. It is red cloth. When my son and son in law brought it to my house the boys started climbing on it and sitting in it. Then it happened...the four year old licked it. After the surprise we laughed. I guess licking it was his way of baptising it into the family.
Do you have a licker at your house? Let me know in the comments. We don't know any others.
