"Bickit"

We've been wondering for months what "bickit" means. We've repeated it, questioned Payton, and looked around wondering. I FINALLY figured it out! He has said it in every room of the house, except the kitchen.

1. Yesterday morning Payton wakes up to nurse at 5:30, finishes, rolls over, "bickit" and falls asleep.
2. Last night I'm carrying him past the crib full of all kinds of stuff because he doesn't sleep there. He's just showered, points to the crib, "bickit", and we continue on to get dressed for bed. No cries or concerns over whatever bickit is.
3. He takes me to his bed to nurse this afternoon, looks under his bed, "bickit". He follows it up with a "oh no" and a "ah gone", shaking his hands because the bickit is all gone. He crawls up on the bed to nurse because milk is way more important that whatever this bickit thing is. (at this point I think I've figured it out but I'm distracted by something and forget to look under the bed)
4. I'm at the computer in the livingroom. He points, smiles (I kid you not!) and says "bickit". Yup, that's a bickit and it's exactly what I thought it was. There's more than one in this house and the one in his room is gone, best I can tell. It probably is under his bed.

What's YOUR guess?
