Is it normal for parents to pick a favorite child among their children?

Yes it is. Personally I think any parent who says they don't have a favorite is lying. Though if it is right. That's a entirely different question which is a "no" more specifically when it's noticeable. If you can't tell then no one will know. If it is then there is a problem

As an adult it is important to properly understand what this question means. The question doesn’t use the word ‘Love’ but instead uses the word ‘favourite’ At various times in a life a parent may favour a child over another for example on a particular child’s birthday or when a child has done something that warrants particular praise or thanks. This is not to say that the parent loves that child any more than the others and this kind of thing normally wouldn’t last particularly long. It should be balanced against the needs of the other children.

By right there should be no favoritism among family. This is because in the world people are already unfair and unkind to other people. The only solace your child have is coming back home to family. And if there is favoritism there too how is your child gonna handle it. Besides all of them are your children, they might not be the same but are unique in their own ways.

Yes. But it doesn't mean they love the others less! Despite being parents, they are individuals as well. They will have specific affinities with some of their children, sometimes because they are alike, sometimes because they are opposite, and sometimes because they remind them of someone they cherish! This is sometimes subject to grief in families, as one child is considered to be favored, and subsequently, the others feel abandoned.

I would say that it is definitely noticed and happened frequent however I wouldn't say favorite child overall. Maybe one child has some favorite traits about things here And the other child has favorite traits other things there. So I wouldn't say there are favorite children overall but that there are favorite traits among children. You like how one likes to cuddle but you like how the other kid is good at bargain shopping. So you wouldn't have a favorite child. You just have favorite traits from each individual child. It's like them having separate interests. . And that's okay. Each child isn't going to be the same.
