What the F do I get my 1yr old?!?!

Be

I can not for the life of me figure out what to get my soon to be 1yr old for her birthday. Complicating matters is that she has a sister that is almost exactly 2yrs older & she has hand me downs from her sister plus 5 girl cousins...what can I get her that she doesn't already have via hand me down?! I know it sounds like a stupid problem to have, but honestly, she doesn't have anything that is just hers...& I'm drawing a blank at what to get her. Any ideas are welcome.
