Yes, he does still like to put it in his mouth - dips his dummy in it and then sticks his dummy in his mouth

But, promptly spits it out because he hates the taste/texture, but then does it again immediately. Silly. He does try to throw it off of the sheet as he likes the sound it makes when it hits the floors (no carpet so it's like a waterfall sound) and I DO need to sit there with him. But I can sit in the room and read a book and not have to play it WITH him the entire time.
The other day I was folding laundry and carried a sheet out that is identical to the one that I use to put the rice on, and he jumped up and quickly started picking up his toys and putting them away. I noticed but was talking to DH and folding this bedsheet at the same time so didn't think much of it. Then he came running back into the room carrying some pots from his plastics cupboard and sat nicely on the floor with them....I sort of thought "

" and then walked out and he FREAKED!!!!!! Like totally screamed and shouted THAT! THAT! THAT!! (only word he knows) and crying and ran over and tugged at the sheet and tried to spread it out on the floor! So I knew what it was he wanted, but now I can't fold bedsheets in front of him anymore. I've also learned not to tell him that we are going to "Play nice" as it got me the same scenario!!! (He heard "play rice" iyswim).
Nicole I find that when he wanders off to something else all I have to do is tell him to use that new thing in the rice - so he is playing cars, gets up to play with his kitchen and I tell him to bring the cups etc over and we will play kitchen in the rice. Then dolls, then little people stuff, then books (open the books up like tents and pour the rice over the sides, etc)...and on and on. Everything gets in there! I've even stopped cleaning it up and now just pull the corners of the sheets up and twist it and stick it in his closet with the rice in the middle!
