Until she learns to count and realizes that one is missing!

You are super lucky. This worked for me until one blankie got "luv'd" with specific tears, and naturally, *that* one was the one, true blankie, and no other would do.

And controuble -? she's old enough for object permanence - maybe she's just not wanting all three at once yet!

Mere has a "clothie", a cloth diaper. She used it in the orphanage and we've had one (at least) ever since. Fortunately, any clothie of the same style would do. We've left clothies behind across the US. We've gone through dozens. Some lost, some worn out, some have taken one too many trips around the backyard (courtesy of Dashy). We've even had a squirel take one up a tree for it's nest. We're down to about a half a dozen. I was hoping that when these were lost or worn, we'd just not get any more, but Mere still uses them at night (with her feet).

As she gets older, she may become very specific about what she wants. You might want to invest in a few more.
