<human>: My 22 month old has two comfort objects - his blankie and an empty bottle. 

Before I go any further, let me defend myself here. We never put any liquid in the bottle and he doesn't actually suck on it. He never has any stomach or gas issues because he's not swallowing air. Basically he just rests the bottle in his mouth and holds it there with his hand. He has refused a pacifier since about 4 months old. 

Anyway, he's almost 2 and is hardly without the blanket and bottle. He doesn't use them much at home except after he's been playing for awhile and wants to chill out with his bottle and blankie on the couch. He does, however, want them at all times when we're someplace new or around new people, which is understandable. 

I know that having a pacifier can start to affect teeth, although he doesn't hold the bottle with his teeth or suck on it, so I'm not sure if it's exactly the same, but nonetheless, we are starting to get some strange looks. 

I'm alright with the blanket going everywhere, but I think it may be time to get rid of the bottle. But, the bottle and blankie HAVE to go together. He throws a fit if he has one and not the other. So I'm not sure how to get ride of essentially *half* of his comfort object. I'm also kind of considering just letting it play out and see if he drops it on his own. But I don't really want a 3 year old walking around with a bottle hanging out of his mouth.

Summarize the given text in a few sentences.
