what would be the reason for my 4 year old son is getting extreme tantrum for uneven things

A. It is a common phase where kids feel that if they will cry through tantrums or misbehave in a public place or in general they will keep crying the parents will get them what they want or any of those things for whatever your child is showing tantrums so suggest the way to deal with it is to regularly and sometimes you have to ignore the behaviour do not get embarrassed with the behaviour of the child the child will learn and understand this is not going to work but overall what is going to work the best as regular counselling
