K's new fascination

well, K is to that age now...She does not enjoy being clothed or diapered. I have found her several times in the last few weeks with her diaper off. Mostly she pulls it off after she has wet or dirtied it. She wants to potty train so bad, but I refuse to potty train until my kids are 2 1/2 yo. She has gone on the potty several times, but I will not take her to the potty several times throughout the day until she is to the magical age of 2.5 yrs. Last week I found her in the family room playing with some beads that I had just bought to use for bean bags (since we can't have beans). This is what it looked like (without the blue oval, though).
