My baby girl is 2.5 year old sometimes she understand opposite things like when i ask her to put her crayons in box she dont understand what to do??? But when I ask her to put all the crayons out of the box she interprets as to put them inside and she properly kept all the crayons inside the box and handed to me???? I am worried for some time being she behaves like this but not all the time. Is she has any psychological problem
