Hi! New to forum. I have a 7yo and 16mo. My 16mo has suddenly become very attached to a building block. He refuses to put it down. When we take it away, he pitches a fit. He's normally a very sweet, cooperative child. Even when he is getting into things, we can simply ask that he put it back, and he will do it. He's very loving and affectionate. He loves to eat and loves his milk, so we've recently tried to "force" him to put it down by giving him his milk or food to see if he will put it down. He still doesn't put it down. He is even going to bed with it now. My question is...should I be worried about this strange attachment to, of all things, a block?
