Ok, I am starting to wonder again if he has some type of undetected hearing loss.
He is sick today. I am having to talk very loudly to him for him to listen and scream to get him to come from another room. I am wondering if he is getting fluid trapped in his ears.
It is making me think of something that happened last june. He had been sick but after the cold started clearing up I noticed he was unusually clumsy. Tripping, falling over. It went away. I know fluid trapped in ears can cause balancing problems....
He also sleeps with a bottle ( which I know is bad ). I heard that can cause glue ear as well.
