If you have or are expecting multiples, how many items did you buy more than one of?

I know that some items are a given, car sets, highchairs, cribs, etc. but I am more interested in the extras like swings, bouncers and toys. My husband and I bought three of the same bouncers and are now looking back thinking it was kind of silly, what are the odds all three babies are going to be content in them all at once, Lol. This also happened with swings, although those were gifts to us. How did you buy for your multiples?
