For each child I buy about five pacifiers. My second child just turned one a few weeks ago, he still chewing the pacifier especially when the teeth are coming in. We are at our last, fifth pacifier, I have know idea where the rest are, he hides them very well. My place is usually clean, so I would figure it shouldn't be hard to loose something. Somehow, our little tricky guy always finds a place to put his pacifier. The last one we look for almost everyday. He would start eating something and throws the pacifier out. The pacifier holder doesn't work for us, it comes right off. It's always like playing scavenger hunt. Hopefully, all the teeth will come in soon and we can throw the last pacifier away.
