My girl is similar but she prefers putting toys away than eating.
When I tell her to do things I don\'t ask it in a way that will lead to no as an answer. For example I don\'t ask \"do you want to do xxx, or not\" because the obvious answer is \"no\". Instead I will say \"do you want to put away a first or b first\" then this will not lead to \"no\" as an answer.
I will always tell my girl if you don\'t put away your toys, they will get lost, instead of \"throwing them away\" because most of the time kids will figure out these are \"empty threats\" and hence stop listening.
