 How to identify if your child is depressed. Here are some of the signs that you will have to look for. One, child can be very irritable at times, sometimes they can be feeling too low, not obeying or not following so whatever the parents or at the schools they are trying to say. Having crying spells, crying most of the days for a significant amount of time. Being very slow in studies or rather you would see that there's a decline in the academics which they were doing very well. And then last but not the least, the child stays in the isolation, not trying to come out of their room, not trying to interact around with the people. It can be with the family or it can be with their friends.
