How can I combat sibling rivilry among my kids and encourage them to love and care about eachother?

give them positive reinforcement when theyre together.. compliment the older one by saying, youre such a good big brother etc..

try playing soccer or football with them both.. you on one team and them on another so they rely on each other as a team..make sure there on the same team so they arenot aginst each other.. they will bond that way.

There is no cure to turn their personalities around and make them "love and care about each other", cause that will never happen. Your older son probably takes after your husband and sees the younger son as weak and unfavorable in all the ways your husband would. The younger son probably takes after you some, but still has a lot his dad in him.

The daughter is most likely an echo of you and want everyone to just get along and be friends.

These three will never love and care about each other. They're siblings, and they would never do that since any siblings have to compete for their parents attention. What is important is that their parents love them all. There will be differences, but in a good home they'll just be petty.

send them on a camp.

Or take them away at least once a year for a week long holiday somewhere in the country. Teach the boys to hunt and fish and look after themselves.

don't worry about it... they're siblings. it happens... they're going to dislike each other now.. but as they grow older they'll get closer. it's natural... i didn't get along with my brother until he moved out of the house.
