My son is 2 years 9 months old. He cries all the time. Means from morning to night. What should i do? I am so exhausted and stressed

A. First of all you should check the iron level for your child and second is to talk to your child to understand what is the problem why is your child crying constantly because once she will get to know what is the situation like why your child is crying it will be easier for you to manage otherwise of course it will be mentally very frustrating and exhausting for a parent
