I just had this a month ago. It's frustrating my dck was also 22 months old. He use to chew on spoons the baby plastic ones then his parents told me not to allow him to have any cause he puts them in his ear. As soon as I took them away he started bitting the kids. The parents were in shock and didn't understand why all of a sudden he started bitting. I mentioned taking away his spoons maybe ?? Lol anyways they were told to give him straws from their therapist. I secretly have him the spoons watched to make sure he didn't put it in his ear. So he always had a spoon, straw or something he liked chewing on at all times. If I missed a bite he went into his high chair for a time out. It took a couple weeks but he stopped. Some parents are so irritating. He dug the straws in his ear more then the spoons. Anyways, goodluck.
