to not visit relatives who more than one hour away until the children are older?

[indiewitch]

Is this unreasonable do you think? We have an 18m dd who is terrible in the car, she basically screams/cries continuously.
I'm thinking of refusing to visit anyone unless I can do it in a day until they are much older, would this be very unreasonable?
I hate this idea that somehow a weekend away somewhere the other side of the country is in any way fun, horrendous journey, v. little sleep at night and then similarly awful trip home. Then back to work and school the next day, all shattered and couple of days later one of us is ill and taking time off work and school.

ROFL at lovechoc!

Can I just say, I've found the sugestions v. helpful and most people v. supportive.
Didn't find the person saying that a child crying/screaming in a car was odd, by the no. of posts here, it's obvious it's quite common.
So thank you for your suggestions.
And I certainly wanted and received honest opions, would expect no less from mumsnet.
Am loving the slow clapping child listening to Radio 4 though, there's hope for dd yet!
