My son never did care for the binky, I tried to get him to use it to sooth him,but nope. He rather have his pooh bear, which is like his verision of the binky. Hes almost Five, and will not sleep with Pooh. I Think, as long as its just a night time thing, it should be fine, its probably a way to calm him, or comfort him, and most likely grow out of it. Once he gets old enough to understand or realise it could be embarassing or just not big boy enough to have it, he will give it up.
