Every suggestion helps; at least you can try something new. My daughter used to do the same thing. But what I did was ignore her. I didn't even say no, cause then she just did it more and thought it was a game. She gave me her sippy cup once instead of throwing it on the floor one time and I smiled really big and in a dramatic way said "thank you" "oh thank you" and told her how sweet she was and gave her a kiss. From then on she always handed me her sippy cup when she had enough. Then as with the food, when she was about to throw it on the floor I would say "can mommy have that?" and low and behold she gave it to me. And I dramatically thanked her and kissed her. It doesn't work all the time, but there is definitely a lot less food thrown on the floor. If you have a dog that would help tremendously! Or keep a little hand vacuum near the food area. Hope this helps. The thank you's also work with things she should not play with, my daughter is always finding dangerous stuff on the floor and the first thing she does is pick it up and hand it over to me. The thing is you have to emphasize the positive and ignore the negative things the kids do, then you are teaching them positive reinforcement. (Took psychology in college) Anyhoo enough of the boring stuff, love the kids, they will eventually learn. I don’t know of any 15 year old throwing food on the floor. Te he
