Is it good to have a favorite kid ?

it isn't bad for the guardians or parents to have a favourite but they shouldn't act on it so obviously that the children start to dislike each other or feel bad about themselves. Having a favourite is almost guaranteed based on how our brain works, so I don't think they're at fault for it.

Children are very reckless and restless. Especially,  the heat inside the house increases when there is a sibling present inside . There is a lot of movement ,activity , problems etc. Whenever there's more than one kid at home, and everytime there comes favouritism.
Whenever there is a sibling , there will be sibling rivalry. And when there is sibling rivalry, there will be fighting amongst the kids.  But how do we stop them from fighting? By giving equality love to all the children.
This can be done by creating a better understanding between the siblings. As for kids, the best way is to reduce the difference between the siblings. They should be treated like twins, favouritism should be strictly avoided as parents,  because this will give birth to jealousy and will increase the gap in understanding of the two kids. There shouldn't be any partiality in buying things for kids or any partiality in upbringing of kids. We should create a friendly environment among the kids. They should be scolded not to fight and most importantly they should be explained and taught not to fight and work as a team to be more efficient in life later.

Hi there, 

Some people often argue about being vocal about having a favourite kid, but is not at all healthy practice as it would bring disrruption in household peace, the other kid would feel discriminated. The equality should be taught at a very tender age & parents should be the initiater of building this specific quality in them.

Hope this helps.

Best Wishes.
