Children that DO NOT get along.

[5 Little Monkeys]

You say that both of these children are great with other kids except each other so it's really just a case of them not liking each other and that is totally fine!! Their behaviour towards each other isn't though. We don't have to like everyone but we must be nice to everyone. Just keep enforcing the "gentle hands", "play nice" rules and keep them separated as much as possible. They shouldn't have to play with each other if they really don't like each other but they also need to learn how to co-exist without all that fighting lol.

Learning to get along with people we don't like is a valuable lesson and one that should be taught young so that the bully behaviours decrease before they get older and become mean little children/teens!

Good luck!
