It's my daughter's 3rd birthday soon. We're having a little party. She's at the age now where she's formed a few special connections with other children at her nursery and in our friendship group, and we'd like to invite those children to her party.
At nursery she is particularly fond of one little girl. My daughter's key worker reports they play together, I've seen them run and hug when they arrive for the day, and when we're at home DD will mention this little girl as her friend.
The little girl is one of a pair of twins, and her brother is also at nursery. He is not friendly with DD - in fact, she quite often says he hit her or pushed her, that her key worker had to tell him 'gentle hands', etc.
I'm aware they're toddlers and they have their skirmishes, so this isn't a major issue day to day. However, I'm torn as to what to do about party invites. If the little boy was unrelated to DD's friend, we wouldn't invite him, as he isn't one of her buddies and we're probably only inviting 2 or 3 kids from her room. But as he is her twin, I worry I'll give the impression he's 'excluded'. Is it OK to invite one twin and not the other, or is that mean?
If any of you more seasoned party throwers could advise me, that would be great.
