Alice Loves Cheetos!
Cheetos are the ONLY snack she routinely says "please" for, she even signs "please" while saying it to increase her probability of receiving one. This is so cute that she is guaranteed to receive Cheetos.
Of course the reason that Cheetos are around for Alice to request, are that her parents are also quite fond of the little snack :-)
BTW - Many Cheetos flavors are Gluten free, etc. Check out the info.
