Not wanting to travel to in laws?

[Nurserymam]

So I have an 3yo DD and have just had another in July. Me and my partner have been together a year this weekend (I know 😬) Our plans for Christmas involve driving 6 hours down to DP family (think we’re north east and they’re south east) through the night Boxing Day night as we literally cannot fit everything in.
Now my partner is in the army so lives here permanently so obviously spends a lot of time with my family, however I have only met his family less than ten times in the last year we’ve been together for distance reasons. I have two sisters who both live 3 hours away with my nephews who I don’t get to see a lot. His family are all younger siblings with their own busy lives so I feel like we won’t see a lot of them over Christmas anyway.
I know he’s got family that he wants to take our DD to meet for the first time but AIBU not wanting to go down? I have a 3 yo who loves seeing her family and I feel awful taking her away from all of her actual family and brand new toys to be with people who she doesn’t really know for a week at Christmas?

@Rudolphtherednoseddog They are, however I'm not sure where well all fit in tbh. 3 bedroom house for 7 adults and two small children is not ideal, and I’m quite concerned where we’ll all fit as there’s definitely not enough room. Also a very boisterous spaniel that my DD is quite frightened of

The plan isn't ideal but it's tricky as you've agreed to it.... I think 7pm-1am car drive will hopefully be okay and at least baby is a few months old now and likes the car. Can you bring a couple of your daughter's favourite new toys with her? Then she can play with the rest when you come back. I get it though, I'd kind of be dreading it too, but it maybe is just one of those things when family live far away. Maybe next time you can invite them?

It's unfortunate but I think you do need to make time for both families. It's always going to be difficult when you have blended families but you have to make some compromises

Perhaps next year your DD will be old enough to stay on her own with your family while you see your DP's family
