The case of the disappearing bottles

I'm trying to get Kate off the bottle so she only gets a couple a day. A few days ago I noticed there were only a few bottles in the cupboard and I thought that was strange but I though maybe the rest were in the sink. This went on for several days and I kept thinking that they were just dirty in the sink . . . even when the sink was empty. I needed to change her sheets yesterday so I moved the crib. Low and behold, 8 bottles under the bed. Hooray!!! The bottles are found!!! I guess I need to realize that if she takes a bottle to bed and naps, a bottle needs to reappear after the bedtime and naps.
