Have you ever looked at your kids and wondered why on earth they are fighting so much? Why can't they play nicely together? Why won't my kids get along?
I was pondering the same thing recently and I had to be honest... I didn't know why.
But then I kept thinking about it, and tried my hardest to remember being a child. It's not that hard, you just have to be honest with yourself and allow yourself to relive those painful childhood memories (and the good ones too).
I can remember being annoyed at my brothers, wanting to be away from them, annoyed at how they were always in my face and angry at anything they ever did wrong.
But what was the real reason I felt that way... I kept thinking.
Well, the truth is I wanted some individual attention from my parents. I wanted them to love ME, not just "the kids". I wanted some one on one time and I craved the loving feeling you get when a parent makes you feel like the most important person in the world and the most loved person in the world. And I can think back to the times I got that. I just wasn't as annoyed by my brothers. I was happier to play with them. I didn't have anger towards them for no reason.
Perhaps your child just needs to know you love HIM or HER. And maybe once they are completely secure in that love, they won't be so annoyed by their siblings.
