Hello, mi son is 3 years old, he has a few weeks where he is obsess with have everything in his place, for example, he has a box with balls, we used to play a lot with the balls, throw each others, play soccer,etc, but now he want always to keep the balls in the box, if i take one he start to cry and be stressed, in a party they gave him a bag with candys, instead want to eat them, he have them in the bag, he doesn't want to open any candy, he want's all his toys in their place, if i say let's plays with that car, no, he want it in the table where we used to leave it, and for many other thngs, also food, if he wants water, i take it from inside the fridge to give him, and he says NO, put it inside again, many things like this, the popcorns for microwave, he love them, i said let's do some, he was crying because i open the popcorn, after a few minutes he satart to eat them and everything normal. What can i do, i am trying to do the opposite, leave all dis ordered (toys, cars, balls) and tell him its ok, but is very hard. i will appreciate any proffesional opinion. thanks
