I wasn't planning to host this Xmas and keep it just the 4 of us. Last year, I hosted for 12. However change in circumstances means that in-laws will now be coming so therefore will invite my family too. My brother has a new partner of 4 months who has children from previous relationships. Her youngest is 2 and will be with her. I've met the new partner twice but not the child.
My brother has children from previous relationships too and unfortunately he won't see them over Christmas.
Now, I'm not sure if my brothers plans for Xmas and he may already be sorted however I don't necessarily feel comfortable inviting new partner and young child I've never met. Personally it feels too soon for me. DM thinks I'm being unreasonable and it's wrong to exclude them from an invite, she also hasn't met the child.
How do I navigate this with DB? Or am I being unreasonable and invite them too?
Not to drip feed but the past two relationships my brother has had have ended badly and with children involved it's been messy. Whilst I hope this relationship works out I'm not ready to get too close to any new partners and any children.
